  • Adsorption of phosphate ion in aqueous solutions by calcined cobalt hydroxide at different temperatures, Fumihiko Ogata, Daisuke Imai, Megumu Toda, Masashi Otani, Naohito Kawasaki, Naohito Kawasaki, Journal of Environmental Chemical Engineering, 3, 3, 1570, 1577,   2015年06月27日, 10.1016/j.jece.2015.05.028, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=84933057026&origin=inward
    概要:© 2015 Elsevier B.V. All rights reserved. In this study, cobalt hydroxide (Co) was calcined at 130 and 150 °C (Co130 and Co150) and the physical properties of Co, Co130 and Co150 were investigated. Co, Co130, and Co150 were characterized by scanning electron microscopy, X-ray diffraction analysis, and thermogravimetric-differential thermal analysis, and the specific surface area, amount of hydroxyl groups, and surface pH were determined. Moreover, the phosphate adsorption capability of cobalt hydroxide and the cobalt hydroxide calcination products was evaluated via examination of the effect of contact time and solution pH, analysis of an adsorption isotherm, and a desorption study. The amount of hydroxyl groups on the adsorbent decreased in order Co (0.62 mmol/g) > Co130 (0.39 mmol/g) > Co150 (0.06 mmol/g). Similarly, the amount of phosphate ion adsorbed decreased in order Co (155.0 mg/g) > Co130 (120.0 mg/g) > Co150 (2.5 mg/g). These results indicated a linear correlation between the amount of phosphate ions adsorbed and the amount of hydroxyl groups on the adsorbent (correlation coefficient: 0.980). Adsorption kinetic data fit the pseudo-second-order kinetic model better than the pseudo-first-order model, and results from the adsorption isotherm studies suggested that phosphate ion adsorption can be well described by both the Freundlich and Langmuir equations. The ideal pH for phosphate ion adsorption was approximately in the range 6.0-9.0, and the mechanism for phosphate ion adsorption involved ion exchange with surface hydroxyl groups onto the adsorbent. Finally, the desorption results indicated that Co has promising potential for use as a renewable adsorbent.
  • Cationic dye removal from aqueous solution by waste biomass produced from calcination treatment of rice bran, Fumihiko Ogata, Daisuke Imai, Naohito Kawasaki, Naohito Kawasaki, Journal of Environmental Chemical Engineering, 3, 3, 1476, 1485,   2015年06月26日, 10.1016/j.jece.2015.05.025, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=84934295024&origin=inward
    概要:© 2015 Elsevier Ltd. All rights reserved. Biomass-derived adsorbents, prepared from rice bran (RB) and treated by calcination at 600, 800, and 1000 °C (RB600, RB800, and RB1000), were characterized in terms of their properties. The adsorption of methylene blue (MB) and crystal violet (CV) on the biomass adsorbents was evaluated. The amount of MB and CV adsorbed was related to the physical properties of the adsorbent. For both dyes, the adsorption capacity increases with time, and the equilibrium time is about 8 and 48 h for uncalcined RB and RB1000, respectively. The adsorption kinetics of dyes is better described by a pseudo-second-order kinetic model. Moreover, the amount of MB or CV adsorbed onto uncalcined RB decreased with increasing temperature, whereas adsorption onto RB1000 increased with increasing temperature. The enthalpies implied by the temperature dependence were ΔH = -4.89 to -54.77 kJ/mol and 11.13-50.21 kJ/mol, for uncalcined RB and RB1000, respectively, which suggested that the adsorption of the dyes onto uncalcined RB or RB1000 should be regarded as physical adsorption, or between physical adsorption and chemical adsorption but dominated by physical adsorption. The equilibrium data of dyes fitted well to the Freundlich adsorption isotherm models. The amount of dyes adsorbed onto uncalcined RB or RB1000 increased at approximately pH 6.0 or http://dx.doi.org/10.0, respectively, which suggests that MB and CV were adsorbed on the surface of the adsorbent through interactions between the electrons of the negatively charged adsorbent surface and the cationic dyes in solution.
  • Properties of novel adsorbent produced by hydrothermal treatment of waste fly ash in alkaline solution and its capability for adsorption of tungsten from aqueous solution, Fumihiko Ogata, Yuka Iwata, Naohito Kawasaki, Naohito Kawasaki, Journal of Environmental Chemical Engineering, 3, 1, 333, 338,   2015年01月01日, 10.1016/j.jece.2014.11.015, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=84920397190&origin=inward
    概要:© 2014 Elsevier Ltd. All rights reserved. Zeolites were produced by hydrothermal treatment of fly ash for 48, 60, and 72 h (referred to as FA48, FA60, and FA72) in alkaline solution. Physical and chemical analyses were performed on the FA samples. Moreover, the amount of tungsten adsorbed on the FA samples, derived from the adsorption isotherms under different pH conditions, and the effect of the contact time on the adsorption were evaluated. Parent FA consisted primarily of mullite crystals, whereas the hydrothermally treated FA48, FA60, and FA72 samples consisted of phillipsite, zeolite X, and zeolite A, respectively. The specific surface areas and pore volumes of parent FA were smaller than those of FA48, FA60, and FA72. FA48 generated the largest specific surface area and pore volume. The saturated amount of tungsten adsorbed on FA48 was greater than that of the other FA samples. Tungsten adsorption was more effective (larger amount) at pH 2.0-3.0 than at pH 6.1-6.5 or pH 11.0-12.0. These results suggest that the tungsten was adsorbed on the surface of FA48 through interactions between the electrons of the positively charged FA48 surface and the tungsten anions in solution. Analysis of the equilibrium adsorption data using the Langmuir and Freundlich equations showed that the correlation coefficient of the Freundlich isotherm was higher than that of the Langmuir model. The data obtained in this study fit more adequately to the pseudo-second-order model than the pseudo-first-order model. Collectively, these results suggest that FA48 is prospectively useful for the adsorption of tungsten from aqueous solutions.

    概要:フライアッシュを加熱処理(FA, FA300, FA500, FA700)およびアルカリ水熱処理(FA48, FA60, FA72)することにより,調湿剤の試作を行った.調湿剤の諸物性として,灰分,比表面積,細孔容積,平均細孔径,X線回折分析,電子顕微鏡写真および水蒸気吸着量について検討した.FA60 (85.7 m2/g)の比表面積は,他の調湿剤に比べ高値を示した.また,FA60の吸・脱湿量は,他の調湿剤に比べ優れており,水蒸気の吸着機構として調湿剤の比表面積,細孔容積および表面の濡れ性が関与していると考えられる.吸・脱湿等温線は,BET式に適合し,FA60の調湿性能は,116.8 mg/g となり,水蒸気の繰り返し吸・脱着に有用であることがわかった.これらのことから,フライアッシュから調湿剤が試作でき,その調湿性能は実用化を考慮した場合,有用であることが示唆された.
  • Adsorption of phosphate ions from aqueous solution of nickel hydroxides calcined at different temperatures, Fumihiko Ogata, Daisuke Imai, Megumu Toda, Masashi Otani, Naohito Kawasaki, e-Journal of Surface Science and Nanotechnology, 12, 404, 409,   2014年08月30日, 10.1380/ejssnt.2014.404, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=84908246914&origin=inward
    概要:© 2014 The Surface Science Society of Japan. Nickel hydroxide (Ni100) and nickel hydroxide, including cobalt (NiCo91), were calcined at different temperatures. These materials were investigated by analyzing data obtained from X-ray diffraction (XRD), scanning electron microscopy, specific surface area, thermogravimetric-differential thermal (TG-DTA) technique, and electron-probe microanalysis. The XRD and TG-DTA data obtained indicated that calcination at 250-270°C can promote the conversion of Ni(OH)2 into NiO, and that cobalt hardly affected the structural changes of nickel hydroxide. The specific surface areas of Ni100 and NiCo91 were determined to be in the range 17.9-148.3 and 21.0-145.1 m2/g, respectively. The specific surface area increased suddenly at 260°C. The amount of phosphate adsorbed onto Ni100 and NiCo91 was measured to be in the range 29.2-44.7 and 29.7-54.0 mg/g, respectively. The amount adsorbed onto Ni100 or NiCo91 was greater than that onto another adsorbent previously reported. The correlation coefficient relationships between the specific surface areas of Ni100 and NiCo91 and the saturated amount of the adsorbed phosphate ions were found to be 0.935 and 0.960, respectively. These results suggested that adsorption of phosphate ions with Ni100 or NiCo91 is related to the specific surface area. Our study demonstrated that Ni100 and NiCo91 can be considered as promising materials for the adsorption of phosphate ions from aqueous solutions.
  • Adsorption of Au(III) from aqueous solution by calcined gibbsite, Fumihiko Ogata, Naohito Kawasaki, Journal of Chemical and Engineering Data, 59, 2, 412, 418,   2014年02月13日, 10.1021/je400888r, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=84894102686&origin=inward
    概要:Gibbsite (GB) was prepared in this work by calcination between (200 and 1000) C (GB200 and GB1000, respectively). Properties of the GBs prepared over this range of temperatures, such as their morphologies, crystallinities, specific surface areas, the number of hydroxyl groups, pore volumes, and mean pore diameters were investigated. The amount of Au(III) adsorbed onto the GBs was also evaluated. Our findings show that the amount of Au(III) adsorbed onto the GBs is related to the specific surface area and the number of hydroxyl groups. In this study, GB400, that is, GB calcined at 400 C, had the largest specific surface area and number of hydroxyl groups, as well as the largest amount of adsorbed Au(III). Furthermore, the most suitable pH for the adsorption of Au(III) onto GB400 was approximately 6.0, and the gold chloro-hydroxy species [AuCl2(OH)2]- was selectively adsorbed at this temperature. The equilibrium for adsorption was reached within 24 h, and the experimental data were fit to the pseudo-second-order model. The adsorption isotherm data were better characterized by the Langmuir model than the Freundlich model. The presence of chloride ions (Cl-) affected the adsorption of Au(III) onto GB400. The increase of ΔG with temperature showed that the adsorption was endothermic and more favorable at higher temperatures. The positive ΔH values also indicated that Au(III) adsorption on GB400 was endothermic. The positive ΔS values suggest an increase in randomness at the solid-solution interface during the adsorption process. GB400 could be used for at least three Au(III) adsorption/desorption cycles. Collectively, these results suggest that GB400 would be useful for the adsorption of Au(III) from aqueous solutions. © 2014 American Chemical Society.
  • Zeolite X produced by hydrothermal treatment of fly ash in an alkaline solution, Fumihiko Ogata, Yuka Iwata, Naohito Kawasaki, e-Journal of Surface Science and Nanotechnology, 12, 23, 25,   2014年02月08日, 10.1380/ejssnt.2014.23, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=84893851748&origin=inward
    概要:Fly ash (FA) was hydrothermally treated in an alkaline solution to produce zeolite X (Z-FA). The properties of the FA and Z-FA were then investigated. The FA consisted of spherical particles of various diameters. The X-ray diffraction patterns of FA and Z-FA showed that the FA mainly consisted of mullite crystals (3Al2O3·2SiO2), while the Z-FA consisted of zeolite crystals. The specific surface area (23.3 m2/g) and pore volume (57.6 μL/g) of the Z-FA were greater than those of the FA (2.7 m 2/g and 12.7μL/g, respectively). The pHpzc of the FA and Z-FA were 7.94 and 9.81, respectively. © 2014 The Surface Science Society of Japan.
  • Adsorption of Pt(IV) and Pd(II) by calcined dried aluminum hydroxide gel from aqueous solution system, Fumihiko Ogata, Naohito Kawasaki, Journal of Environmental Chemical Engineering, 1, 4, 1013, 1019,   2013年12月01日, 10.1016/j.jece.2013.08.011, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=84888404592&origin=inward
    概要:In this study, calcined dried aluminum hydroxide gels (Gs) were prepared at 300-1000 C (G300-G1000) as adsorbents. The properties of the adsorbents (i.e., XRD patterns, SEM images, specific surface areas, and number of hydroxyl groups) were investigated. The adsorption of Pt(IV) and Pd(II) onto Gs at different temperatures was evaluated. Calcination transformed virgin G into γ- and α-alumina. G600 had the largest specific surface area (107.2 m 2/g) and number of hydroxyl groups (1.12 mmol/g) of the Gs. G600 also adsorbed the greatest amount of Pt(IV) and Pd(II). The amount of Pt(IV) and Pd(II) adsorbed was more closely related to the number of hydroxyl groups than the specific surface area. The adsorption mechanism of Pt(IV) and Pd(II) onto G600 mainly involved ion exchanges. The optimal pH for the adsorption of Pt(IV) and Pd(II) onto G600 was ∼5.0, which suggests that [PtCl5(OH)] 2- and [PdCl3(OH)]2- species are suitable for adsorption. Pt(IV) and Pd(II) compete with chloride ions for adsorption sites on G600 in the aqueous solution system. The adsorption of Pt(IV) and Pd(II) onto G600 reached equilibrium within 24 h. The experimental data fit the pseudo-second-order model (correlation coefficient: 0.986-0.995) better than the pseudo-first-order model (correlation coefficient: 0.879-0.973). Moreover, the Weber-Morris plot also was evaluated. The adsorption isotherms of Pt(IV) and Pd(II) onto G600 fit the Freundlich and Langmuir models, respectively. Thus, G600 is useful for the adsorption of Pt(IV) and Pd(II) in aqueous solution. © 2013 Elsevier Ltd. All rights reserved.
  • Lead (II) adsorption on chemically modified activated carbon in aqueous solution, Fumihiko Ogata, Yuka Iwata, Naohito Kawasaki, e-Journal of Surface Science and Nanotechnology, 11, 93, 98,   2013年08月31日, 10.1380/ejssnt.2013.93, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=84885075569&origin=inward
    概要:In the present study, we developed modified activated carbon (KL) for the adsorption of Pb (II). Chemically modified activated carbons (KL-A and KL-B) were prepared by nitric acid and ethylenediamine treatments, respectively. The properties (specific surface area, pore volume, mean pore diameter, acidic or basic functional groups, and pH) of KL, KL-A, and KL-B were investigated by various methods. Contact time, adsorption isotherms, and recovery of Pb (II) were evaluated. Equilibrium adsorption on KL and KL-B or KL-A was reached in about 12 h and 5 h, respectively. The experimental data was fitted to pseudo-second order model and compared with the pseudo-first order model. The optimal pH conditions for the adsorption of Pb (II) was pH = 5.1-5.5. These data were fitted to Freundlich and Langmuir models. Moreover, the adsorption mechanism of Pb (II) on KL-A was related to the ion exchange with acidic functional groups. It would be possible to recover Pb (II) by using nitric acid. The results suggest that KL-A would be useful in the adsorption of Pb (II). © 2013 The Surface Science Society of Japan.
  • Development of actual dyestuff wastewater treatment by ozone with carbonaceous materials produced from waste fiber, Naohito Kawasaki, Hisato Tominaga, Fumihiko Ogata, Sen'i Gakkaishi, 69, 7, 125, 131,   2013年08月05日, 10.2115/fiber.69.125, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=84880885330&origin=inward
    概要:The methylene blue and dyestuff removal efficiency in a textile factory by ozonation and/or carbonaceous material treatment was investigated. Three kinds of carbonaceous materials were prepared from wool (WL), polyester (PET), and cotton (CT) discharged from the textile factory. The physical properties of the carbonaceous materials were very different. The specific surface area and pore volume of WL were the lowest, while those of CT were the highest. The dyestuff removal efficiency from actual dyestuff water was the highest when using the carbonaceous material (CT) prepared from cotton waste fiber. The decreases in the chromaticity, turbidity, COD, and TOC of the actual dyestuff wastewater depended upon the mean pore diameter of the carbonaceous material. The COD and TOC of the actual dyestuff wastewater were only slightly decreased by ozonation. The ozonation with CT would be useful for the removal of the dyestuff from actual textile wastewater. These results indicated that the waste cotton fiber could be converted into a carbonaceous material as an adsorbent for the removal of dyestuff from actual wastewater.

    概要:Gibbsite calcined at 400°C (GB400) was prepared, and its ability to adsorb rhodium(III) was investigated. Optimal pH, effect of contact time, temperature, adsorption isotherms, and recovery percentage were evaluated. The optimal pH was 6.3. The adsorption equilibrium was achieved within 24 h. The adsorption rate was found to be of pseudo-first order. The experimental data were fitted to both the Freundlich (r = 0.90-0.93) and Langmuir (r = 0.94-0.96) equations. The amount of rhodium(III) adsorbed decreased with increasing temperature. Rhodium(III) being adsorbed from phosphate or sulfate plating solution was recovered using hydrochloric acid and sodium hydroxide solutions at 1, 10, and 100 mmol L-1. © 2013 © 2013 Taylor & Francis.
  • Adsorption of Pt(IV) and Pd(II) from aqueous solution by calcined gibbsite (Aluminum Hydroxide), Fumihiko Ogata, Kenji Inoue, Hisato Tominaga, Yuka Iwata, Ayaka Ueda, Yuko Tanaka, Naohito Kawasaki, e-Journal of Surface Science and Nanotechnology, 11, 40, 46,   2013年03月23日, 10.1380/ejssnt.2013.40, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=84875542746&origin=inward
    概要:In the present study, calcined gibbsite (GB) was prepared by calcination treatment between 200 and 1000°C (GB200-GB1000). The properties of GBs (i.e., the amount of hydroxyl groups, specific surface area, mean pore diameter, and pore volume) were evaluated. GB400 had the highest amount of hydroxyl groups (0.46 mmol/g), as well as the highest specific surface area (295.3 m2/g) and micropore volume (0.036 mL/g). It also provided the highest amount of the adsorbed Pt(IV) and Pd(II), which suggests that the adsorption of Pt(IV) and Pd(II) onto GB is related to the amount of hydroxyl groups, specific surface area, and micropore volume. The optimal pH values for the adsorption of Pt(IV) and Pd(II) onto GB400 were 4.5-5.0 and about 6.0, respectively. The equilibrium adsorption of both cations onto GB400 was reached within 30 min. Moreover, the experimental data of the adsorption of Pt(IV) and Pd(II) onto GB400 was fitted by pseudo-second-order model (r = 0:997-0.999) and the Langmuir equation (r = 0:934-0.953). The calculated thermodynamic parameters δG, δH, and, δS indicate that the adsorption of Pt(IV) onto GB400 is feasible, spontaneous, and exothermic. In addition, the amount of Pt(IV) and Pd(II) adsorbed onto GB400 decreased with increasing chloride ion concentration. © 2013 The Surface Science Society of Japan.

    概要:Kalimate® is often administered to patients via a simple suspension method by feeding tube. However, this method has a low recovery ratio and tube obstruction can occur. In this study, we investigated whether adding dextrin to decrease the adhesiveness and dispersibility improves the low recovery ratio and reduce tube obstruction. The addition of 0.6% dextrin significantly increased the dispersibility and fluidity of kalimate® compared to the dispersibility and fluidity of kalimate in purified water, but the addition of 0.1% and 0.2% dextrin did not. On the other hand, the 0.1 - 0.6% dextrin improved the low recovery ratio of kalimate® in the simple suspension method by feeding tube. These results show that the addition of dextrin improves the low recovery ratio and prevents tube obstruction in the simple suspension method of kalimate®. In addition, it was suggested that the decrease in recovery ratio of kalimate® is related to the adhesiveness, and the increase of dispersibility suppressed the tube obstruction in the simple suspension method by feeding tube. These findings provide significant information that can be used in improving the low recovery ratio and tube obstruction in the simple suspension method by feeding tube.
  • Production of granulated boehmite by compression and its adsorption of phosphate in a single-solution system, Fumihiko Ogata, Hisato Tominaga, Yuka Iwata, Ayaka Ueda, Yuko Tanaka, Naohito Kawasaki, e-Journal of Surface Science and Nanotechnology, 10, 518, 520,   2012年09月22日, 10.1380/ejssnt.2012.518, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=84867202312&origin=inward
    概要:In this study, powdered boehmite (AlO(OH)) was compressed to obtain a granulated form without using a binder. The granulated product was assessed via SEM imagery, TG-DTA, specific surface area, surface pH, and hydroxyl groups. The SEM images showed that powdered BE could be successfully granulated by compression without binders. TG-DTA showed that dehydration of adhesion and bound water occurred at 96.0 and 394.6°C, respectively. The amount of phosphate adsorbed onto granulated boehmite increased with temperature, indicating a chemisorption mechanism. Moreover, equilibrium adsorption was reached within 20-24 h. Adsorption kinetics data was fitted to the pseudo-second-order model. © 2012 The Surface Science Society of Japan.
  • Adsorption of nitrate, nitrite, and fluoride ions by carbonaceous material produced from coffee grounds in a complex solution system, Fumihiko Ogata, Hisato Tominaga, Moe Kangawa, Kenji Inoue, Yuko Tanaka, Ayaka Ueda, Yuka Iwata, Naohito Kawasaki, e-Journal of Surface Science and Nanotechnology, 10, 493, 498,   2012年09月08日, 10.1380/ejssnt.2012.493, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=84866351983&origin=inward
    概要:Carbonaceous materials produced from coffee ground (virgin CG, CG600, CG800, and CG1000) were prepared. Specific surface areas, mean pore diameters, pore volumes, and SEM images of the CGs were investigated. The specific surface areas were in the order CG1000 (23.5 m 2/g) < CG800 (31.5 m 2/g) < CG600 (52.6 m 2/g), and the mean pore diameters were in the order CG600 (77.0 Å) < CG800 (139.3 Å) < CG1000 (273.8 Å). The amounts of nitrate, nitrite, and fluoride ions adsorbed in a single solution system were greater than the amounts adsorbed in a ternary solution system; this indicated that the ions were competitively adsorbed onto the CGs in the complex solution system. Moreover, the adsorption mechanism was ion exchange with chloride ion onto the CGs in a 1:1 ratio. Adsorption isotherms were fitted to both the Freundlich equation and the Langmuir equation. The amounts adsorbed increased with increasing temperature. The adsorption affinities onto the CGs were in the order nitrate ion < nitrite ion < fluoride ion. The most suitable breakthrough curve conditions were Space velocity: 4.24 1/h and Linear velocity: 0.38 m/h. Thus, carbonaceous materials produced from coffee grounds were useful for the adsorption of nitrate, nitrite, and fluoride ions in a ternary solution system. © 2012 The Surface Science Society of Japan.
  • Evaluation of carbonaceous material produced from fireproofed cotton and its adsorption of Methylene blue, Fumihiko Ogata, Hisato Tominaga, Moe Kangawa, Kenji Inoue, Yuko Tanaka, Yuka Iwata, Ayaka Ueda, Naohito Kawasaki, e-Journal of Surface Science and Nanotechnology, 10, 374, 378,   2012年07月21日, 10.1380/ejssnt.2012.374, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=84864433123&origin=inward
    概要:We report herein on the fabrication of carbonaceous material produced from cotton treated with Tricresyl phosphate (TCP) for fireproofing and its evaluation for adsorbing Methylene blue (MB). We prepared two carbonaceous materials: cotton calcined at 900 ? C (CT900) and cotton calcined at 900 ? C with TCP (F-CT900). These materials were evaluated in terms of their scanning electron microscope images, specific surface area, pore volume, mean pore diameter, and solution pH. We found that the specific surface area of F-CT900 (1492 m2/g) is greater than that of CT900 (910 m2/g), and that the mean pore diameter of F-CT900 (2.41 ?A) is smaller than that of CT900 (9.09 ?A). The adsorption of MB onto CT900 and F-CT900 reached equilibrium within 5 h. We fitted the experimental data with the pseudo-second-order model and obtained correlation coefficients between 0.993 and 0.999. We found that more MB adsorbed onto F-CT900 (about 650 mg/g) than onto CT900 (about 350 mg/g). We also fitted these experimental data with both the Freundlich and Langmuir equations. Thus, carbonaceous material for MB removal could be produced from fireproofed cotton, and it is useful for the purification of dye solution systems. © 2012 The Surface Science Society of Japan.
  • Granulation of gibbsite with inorganic binder and its ability to adsorb Mo(VI) from aqueous solution, Fumihiko Ogata, Hisato Tominaga, Hitoshi Yabutani, Atsushi Taga, Naohito Kawasaki, Toxicological and Environmental Chemistry, 94, 3-4, 650, 659,   2012年04月01日, 10.1080/02772248.2012.671325, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=84859753162&origin=inward
    概要:In this study, we prepared a new adsorbent and evaluated its ability to adsorb Mo(VI). Gibbsite was granulated with colloidal alumina or colloidal silica. The amount of Mo(VI) adsorbed onto granular gibbsite with a binder, effect of contact time and pH on the adsorption of Mo(VI), and column experiments were investigated. The amount of Mo(VI) adsorbed was greater in the order of ST12 (colloidal silica, 12%) < AS10 (colloidal alumina, 10%) < GB400 (calcined gibbsite at 400°C). Adsorption isotherms data were fitted to the Freundlich equation (correlation coefficient: 0.941-0.978), suggesting monomolecular adsorption on a heterogeneous surface. The amount of Mo(VI) adsorbed onto granular gibbsite with a binder was correlated with the amount of hydroxyl groups rather than the specific surface area. The adsorption rate data of Mo(VI) were fitted to the pseudo-second-order equation, which indicated that the rate limiting step may be chemisorption. Recovery of Mo(VI) using AS10 packed in a column was 95.6%. After five adsorption and desorption steps, adsorption and desorption ability of Mo(VI) using AS10 was unchanged. These results suggest that AS10 packed in a column could be useful for the recovery of Mo(VI). © 2012 Copyright Taylor and Francis Group, LLC.

    概要:The effective use of activated carbon as oral adsorbent in the primary treatment of acute acetaminophen poisoning was studied. The adsorption characteristics of acetaminophen onto activated carbons in presence of sorbitol were investigated in vitro. Both the equilibrium amount adsorbed and the removal rate of acetaminophen onto activated carbon were decreased with the increase of sorbitol concentration in solutions. The sorbitol concentration independency of the inhibition to the acetaminophen adsorption was recognized. It was concluded that the addition of sorbitol to the suspension of activated carbon inhibited the acetaminophen adsorption by activated carbon.
  • Properties of carbonaceous material produced from cotton and its dye adsorption capabilities, Fumihiko Ogata, Hisato Tominaga, Moe Kangawa, Kenji Inoue, Naohito Kawasaki, e-Journal of Surface Science and Nanotechnology, 9, 380, 385,   2011年10月15日, 10.1380/ejssnt.2011.380, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=80054737039&origin=inward
    概要:In this study, methylene blue (MB), orange II (ORII), and indigo carmine (IC) were used as adsorbates. Untreated (CT) and treated cotton (CT400, CT600, CT800, and CT1000) were prepared from waste cotton, and their respective physical (i.e., specific surface area, pore volume, and mean pore diameter) and chemical properties (i.e., yield percentage, base consumption, and amount of pH solution added to the adsorbent) were investigated. Scanning electron microscope images of CT, the adsorption rate, and the adsorption isotherm were also analyzed. The specific surface area, pore volume, and mean pore diameter of CT1000 was greater than that of other CT varieties, indicating that the pores on the CT surface were generated by carbonization. Additionally, yield percentage and base consumption decreased because of carbonization. Equilibrium adsorption (i.e., MB, ORII, and IC) was reached within 12 h. The experimental data were fitted to a pseudo-second-order model, suggesting that the adsorption might be a chemisorption process, for which the correlation coefficient, R, equals 1.000. The amount of dye adsorbed onto CT1000 was as follows: IC (290 mg/g) > MB (446 mg/g) ∼ ORII (452 mg/g). These experimental data were fitted to the Freundlich equation. The present study implies that the adsorbent for dye removal can be produced from waste cotton and that it is useful for the purification of dye solution systems. © 2011 The Surface Science Society of Japan.
  • 粒子サイズの異なる活性炭によるアセトアミノフェンの吸着特性に関する基礎的研究, 棚田 成紀, 中村 武夫, 川崎 直人, 薬学総合研究所紀要, 81, 10, 55, 61,   2001年12月01日, 10.1080/02772240109359027, http://ci.nii.ac.jp/naid/40005013589
    概要:Adsorption characteristics of acetaminophen onto activated carbon of varying particle sizes was investigated for emerging treatment of acute poisoning in vitro. No difference in the equilibrium amount of acetaminophen adsorbed among activated carbon of varying particle size was observed. This result could be explained by the properties of activated carbon. The smaller the particle size of activated carbon, the faster the acetaminophen was removed. It was assumed that the increase of contact surface area (external surface area) due to smaller particle size accelerated the adsorption of acetaminophen onto activated carbon.

  • Removal of NO- 3 -N and NO- 2 -N with coffee grounds by ion exchange, Fumihiko Ogata, Hitoshi Yabutani, Hisato Tominaga, Isao Yamaguchi, Naohito Kawasaki, Kagaku Kogaku Ronbunshu, 36, 4, 293, 298,   2010年07月01日, 10.1252/kakoronbunshu.36.293, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=77955353623&origin=inward
    概要:To investigate the recycling of coffee grounds (CGs), the surfaces of CGs were modified with CaCl2 solution, and the adsorption mechanism of NO- 3-N and NO- 2-N on these surfaces was evaluated. Maximun adsorption of NO- 3-N and NO-2 -N was observed with CGs carbonized at 600oC (CG600), and the amounts adsorbed increased with temperature, at the time of adsorption, reaching equilibrium after 24h. The amount of chloride ions eluted from CG600 increased with the amount of NO- 3-N and NO- 2-N adsorbed. The adsorption isotherms of NO- 3-N and NO- 2-N were fitted by the Freundlich and the Langmuir equations. These results indicated that NO- 3- N and NO- 2-N were adsorbed onto CG600 by ion exchange. CGs treated with CaCl2 solution can be utilized for the removal of NO- 3-N and NO- 2-N from drinking water. © 2010 The Society of Chemical Engineers, Japan.
  • Practical safety of using essential medicines and their market products in Thailand, Siriporn Burapadaja, Naohito Kawasaki, Suporn Charumanee, International Journal of Risk and Safety in Medicine, 22, 1, 17, 25,   2010年03月24日, 10.3233/JRS-2010-0488, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=77949553362&origin=inward
    概要:Safety is one of the very important elements of medicines, especially in daily practice. It is expected that the medicines listed by the Thai Essential Medicine Lists (EML) and their market products registered by the Thai Food and Drug Administration (FDA) should be comparable with respect to practical safety. The objective was to investigate if there are differences in practical safety between anti-infective essential medicines and their products assigned by the two authorities in Thailand. Data were based on Thai EML, Thai FDA registration, and Thailand Index of Medical Specialities 2008. Results showed that Thai EML and Thai FDA divided anti-infective items (n = 101) and their products into groups varying in practical safety. Two thirds of the items and their products were comparable with respect to practical safety, but one third of them were not. The products of the latter were defined as having a lower practical safety compared to their corresponding items. This study has demonstrated that there are differences in practical safety between several essential medicines and their products. Consistent practical safety is very necessary for safe use of anti-infective products. Thus, there should be deliberations between the two authorities to reconsider the practical safety of these items and their products. © 2010 - IOS Press and the authors. All rights reserved.
  • Removal of cadmium and copper by vegetable biomass treated with hydrochloric acid, Naohito Kawasaki, Hisato Tominaga, Fumihiko Ogata, Kazuaki Kakehi, Chemical Engineering Journal, 157, 1, 249, 253,   2010年02月15日, 10.1016/j.cej.2009.11.028, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=75149117286&origin=inward
    概要:Food waste is discharged abundantly, and while some of it is reused, most is incinerated. The recycling of soybean waste and wheat bran as vegetable biomass needs to become established, and the ability to remove Cd2+ and Cu2+ by vegetable biomass needs to be estimated. The estimations performed here revealed that the amounts of Cd2+ and Cu2+ adsorbed onto untreated vegetable biomass were larger than those adsorbed onto defatted biomass. This indicates that the adsorption of Cd2+ and Cu2+ onto vegetable biomass may depend on fat content. On the other hand, the elution percentage of vegetable biomass increased as the concentration of hydrochloric acid increased. The elution is due to the degradation of protein in the biomass by the acid. The amounts of Cd2+ and Cu2+ adsorbed decreased as more than 0.10 mol/L of the concentration of hydrochloric acid increased. Cd2+ and Cu2+ are adsorbed on vegetable biomass by their adsorption onto protein. The amounts of Cu2+ adsorbed onto soybean waste and wheat bran in a binary-solution system are larger than those in a single-solution system. However, less Cd2+ was adsorbed onto wheat bran in the binary system than in the single one. These results indicated that the amount of Cu2+ adsorbed increases in the presence of Cd2+. Either the adsorption of Cd2+ onto wheat bran is inhibited by Cu2+ or the adsorptions of Cd2+ and Cu2+ onto the biomass were affected by each other. © 2009 Elsevier B.V. All rights reserved.
  • Adsorption ability of arsenic (III) and chromium (VI) onto granular GB | Japanese Source, Fumihiko Ogata, Naohito Kawasaki, Mineaki Kabayama, Kazuaki Kakehi, Kagaku Kogaku Ronbunshu, 35, 1, 42, 46,   2009年09月18日, 10.1252/kakoronbunshu.35.42, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=70249095623&origin=inward
    概要:Arsenic (III) and chromium (VI) are known to be harmful for human health. In this study, gibbsite (GB) was granulated using ethyl cellulose or alumina sol 520 for the removal of arsenic (III) and chromium (VI). Two kinds of granular GBs had the ability to adsorb arsenic (III) and chromium (VI), with arsenic (III) being adsorbed in greater amount. Use of ethyl cellulose to prepare granular GB may not be economically suitable, because the production process is complex and requires the use of solvent. The amount of arsenic (III) and chromium (VI) adsorbed onto GB was slightly decreased by the granulation. The amount of arsenic (III) adsorbed onto granular GB in a binary solution system was greater than that in single solution system, while the amount of chromium (VI) adsorbed was similar in both systems. The adsorption mechanism of arsenic (III) and chromium (VI) is thought to dependent on the affinity between the metals and the surface or porosity of granular GB. The prepared GB could be utilized for removal of arsenic (III) or chromium (VI) in an aqueous environment. © 2009 The Society of Chemical Engineers, Japan.
  • Factors associated with the market availability of systemic anti-infective products in Thailand (no. 743), Siriporn Burapadaja, Naohito Kawasaki, Suporn Charumanee, Ornanong Kittipongpatana, Fumihiko Ogata, Journal of Public Health, 17, 4, 251, 256,   2009年08月01日, 10.1007/s10389-009-0247-8, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=68249160898&origin=inward
    概要:Background: Despite the fact that the market availability of medicines has been recognized as one of the most important components in the health-care system, its association with other factors is still in doubt. Objective: This study aimed at determining the factors associated with the number of trade names and products of systemic anti-infective medicines available for the market in Thailand. Methods: A cross-sectional study on the data from the Thai National List of Essential Medicines (Thai EML) 2008 and Thailand Index of Medical Specialties 2008 was undertaken. Results: Results showed a total of 702 trade names and 1,262 products from 137 generic drugs. Half of the products belonged to the classes of beta-lactam antibacterials (39%) and quinolone antibacterials (11.3%). The significant factors found were dosage forms of medicines, manufacturer types and category. The generic drugs that were prepared in more than one dosage form, produced by local manufacturers and categorized as essential medicines (EMs) would have a greater number of trade names and products than those done in one dosage form by foreign manufacturers and as non-EMs. Conclusion: There are at least three factors associated with the number of trade names and products of systemic anti-infective medicines, which include dosage forms of medicines, manufacturer types and EM category. These factors have involved the technical issue, private sector and Thai EML. One suggestion from this finding is to use the Thai EML as a means to control the market availability of systemic anti-infective products in the country. © 2009 Springer-Verlag.
  • Relationship between anion adsorption and physicochemical properties of aluminum oxide, Naohito Kawasaki, Fumihiko Ogata, Kouzou Takahashi, Mineaki Kabayama, Kazuaki Kakehi, Seiki Tanada, Journal of Health Science, 54, 3, 324, 329,   2008年06月01日, 10.1248/jhs.54.324, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=44849109577&origin=inward
    概要:This study investigated the adsorption capacity and adsorption mechanism of phosphate by calcined aluminum oxide (GB) at temperatures of 200 to 1150°C. The results showed that GB and GB calcined at a temperature of 200°C exhibited almost no adsorption capacity, and GB calcined at temperatures of 300 or 400°C exhibited the highest adsorption capacity. After that, adsorption capacity tended to decrease with increasing calcination temperature. The specific surface area and the concentration of surface hydroxyl groups exhibited the highest values in GB calcined at temperatures of 300 and 400°C. From the above facts, it is conjectured that the specific surface area and concentration of surface hydroxyl groups contribute to the adsorption of phosphate in calcined GB. The results of X-ray diffraction showed that the structure of GB changed drastically at temperatures of 200 to 300°C and 900 to 1000°C. Also, it was evident that phosphate was adsorbed selectively even in complex solution systems containing chloride, nitrate, sulfate, hydrogen carbonate and phosphate ions, and that calcined GB is suitable for adsorption of phosphate. For the adsorption of phosphate, it was found that the optimum pH is around 4. When calcined GB is suspended in purified water, it is thought that hydroxyl groups form through dissociative adsorption with water molecules, and that these hydroxyl groups conduct ion exchange with phosphate.
  • Structure transformation of gibbsite by calcination, Fumihiko Ogata, Naohito Kawasaki, Mineaki Kabayama, Takeo Nakamura, Seiki Tanada, e-Journal of Surface Science and Nanotechnology, 4, 267, 269,   2006年03月11日, 10.1380/ejssnt.2006.267, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=33644975364&origin=inward
    概要:Gibbsite, which is aluminum oxide, was calcined in the temperature range from 200 to 1150°C, and the relation between the calcination temperature and various properties of gibbsite has been examined. It is speculated based on the results of TG-DTA experiment that the structure of gibbsite changed greatly at a calcination temperature of 282.7° C. Specific surface area of gibbsite kept on increasing as the calcination temperature is elevated up to 400° C, where it reached a maximum value. In the range where the calcination temperature is higher than 400° C, specific surface area, decreased as the temperature was elevated further. In addition, it became evident from the results of XRD measurement that in the calcination temperature range lower than 200° C, the crystal kept gibbsite structure, but it changed to the structure of aluminum oxide of transition type above 300° C. and that it changed further to the structure of stable aluminum oxide when the calcination temperature was elevated over 1000°C. From these results, it is verified that by making use of the fact that the structure of gibbsite changes greatly in the calcination temperature range from 300 to 400° C, a novel adsorbent having boehmite structure can be produced. © 2006 The Surface Science Society of Japan.
  • Indigo carmine removal by charcoal from rice bran as an agricultural by-product, T. Nakamura, N. Kawasaki, S. Tanada, T. Tamura, Y. Shimizu, Toxicological and Environmental Chemistry, 87, 1/4, 321, 327,   2005年07月01日, 10.1080/02772240500126952, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=30344458477&origin=inward
    概要:On the utilization of agricultural by-product, charcoal from rice bran was produced. The adsorption characteristics of indigo carmine onto charcoals from rice bran were investigated by the batch method. The yield and surface area of charcoal were decreased and increased with increase of carbonization temperature, respectively. The removal ratio of indigo carmine was high with the charcoal carbonized at higher temperature. In the relationship between the amount of indigo carmine adsorbed and the square root of elapsed time, a good linearity was recognized. The kinetic constant of adsorption removal for indigo carmine was rapid in the charcoal carbonized at higher temperature. The adsorption characteristics for indigo carmine removal by charcoal from rice bran were dominated by the value of their surface area. © 2005 Taylor & Francis.
  • Adsorption/desorption characteristics of phosphate ion onto calcined boehmite surface, Mineaki Kabayama, Naohito Kawasaki, Takeo Nakamura, Seiki Tanada, e-Journal of Surface Science and Nanotechnology, 3, 63, 69,   2005年02月20日, 10.1380/ejssnt.2005.63, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=18444382041&origin=inward
    概要:Boehmite (aluminum oxyhydroxide, BE) selectively adsorbs phosphate ion. Recently, we studied the recovery efficiency of phosphate ion and the adsorption/desorption mechanism by calcining the BE surface in the temperature range of 200-1150°C. As a result, the amount of phosphate ion adsorbed/desorbed by BE at a calcining temperature of 400-700°C exhibited a higher value than the BE at other calcining temperatures, and the recovery efficiency of the phosphate ion was 90% or higher. On the other hand, the amount of phosphate ion adsorbed/desorbed onto BE at a calcining temperature of 1100°C or higher exhibited a lower value than the BE before calcining. Based on the phosphate ion adsorption/desorption behavior results, and the XRD and FT-IR results, it was determined that when the calcined BE is suspended in water, water molecules are dissociated, producing hydroxyl groups on the surface, and these hydroxyl groups exchange ions with the phosphate ion, thus the amount of phosphate adsorbed ion reaches a maximum. The phosphate ion adsorbed by BE was adsorbed by a sodium hydroxide solution, just like the BE before calcination. It became evident that by calcining BE, it is possible to obtain an adsorbent with a high phosphate ion recovery efficiency. © 2005 The Surface Science Society of Japan.
  • Removal of lead ions in drinking water by coffee grounds as vegetable biomass, Toshimitsu Tokimoto, Naohito Kawasaki, Takeo Nakamura, Jyunichi Akutagawa, Seiki Tanada, Journal of Colloid and Interface Science, 281, 1, 56, 61,   2005年01月01日, 10.1016/j.jcis.2004.08.083, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=9644255782&origin=inward
    概要:In an attempt to reuse food waste for useful purposes, we investigated the possibility of using coffee grounds to remove lead ions from drinking water. We studied the lead ion adsorption characteristics of coffee beans and grounds by measuring their fat and protein content, adsorption isotherms for lead ions, and adsorption rates for lead ions. The number of lead ions adsorbed by coffee grounds did not depend on the kind of coffee beans or the temperature at which adsorption tests were performed. The rate of lead ion adsorption by coffee grounds was directly proportional to the amount of coffee grounds added to the solution. When coffee grounds were degreased or boiled, the number of lead ions decreased. When proteins contained in coffee grounds were denatured, the lead ion adsorption was considerably reduced. The lead ion adsorption capacity of coffee grounds decreased with increased concentration of perchloric acid used for treating them and disappeared with 10% perchloric acid. The experiments demonstrated that proteins contained in coffee beans depend upon the adsorption of lead ion. The present study gave an affirmative answer to the possibility of using coffee grounds, an abundant food waste, for removing lead ions from drinking water. © 2004 Elsevier Inc. All rights reserved.
  • Adsorption of fluoride ions onto carbonaceous materials, Ikuo Abe, Satoshi Iwasaki, Toshimitsu Tokimoto, Naohito Kawasaki, Takeo Nakamura, Seiki Tanada, Journal of Colloid and Interface Science, 275, 1, 35, 39,   2004年07月01日, 10.1016/j.jcis.2003.12.031, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=2442698693&origin=inward
    概要:The characteristics of fluoride ion adsorption onto carbonaceous materials were derived as adsorption isotherms at different temperatures and in different pH solutions. The fluoride ion was adsorbed into pores in carbonaceous materials produced from wood; the larger the specific surface area, the more fluoride ions adsorbed. Bone char was the most effective adsorbent. The composition of bone char includes calcium phosphate, calcium carbonate, and so on. This suggests that the phosphate ion in bone char was exchanged with a fluoride ion. Moreover, the mechanism of fluoride ion adsorption onto bone char is clearly chemical in nature because the amount of fluoride ion adsorbed onto bone char increased with increasing temperature and decreasing pH. The amount of fluoride ion adsorbed onto bone char was also shown to depend on the concentration of sodium chloride in solution because of the "salting-out" effect. The adsorption of fluoride ion onto bone char is endothermic. Bone char can be utilized to remove fluoride ions from drinking water. © 2004 Elsevier Inc. All rights reserved.
  • Accelerating effect of sodium chloride on mexiletine adsorption onto activated charcoal, T. Nakamura, Y. Oida, N. Kawasaki, S. Tanada, T. Tamura, Toxicological and Environmental Chemistry, 86, 1/4, 205, 209,   2004年01月01日, 10.1080/02772240400007096, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=13444309506&origin=inward
    概要:The effective use of activated charcoal as an oral adsorbent for primary treatment of acute poisoning was investigated in vitro by evaluating the characteristics of mexiletine, an anti-arrhythmic drug, adsorbed onto activated charcoal in the presence of sodium chloride solutions at various concentrations. The equilibrium amount of mexiletine adsorbed onto activated charcoal was increased by the addition of sodium chloride. In particular, there was a marked increase in the amount adsorbed from a solution of lower mexiletine concentration. The removal rate is another important factor in the evaluation of activated charcoal, and a rapid decrease of mexiletine concentration by the addition of sodium chloride was recognized. The acceleration of mexiletine adsorption onto activated charcoal by the addition of sodium chloride was due to the occurrence of salting-out. It could be concluded that the administration of activated charcoal suspended in saline solution was more effective in the primary treatment of acute poisoning by mexiletine overdose.
  • Decolorization of acidic dye by charcoal from coffee grounds, Takeo Nakamura, Toshimitsu Tokimoto, Takamichi Tamura, Naohito Kawasaki, Seiki Tanada, Journal of Health Science, 49, 6, 520, 523,   2003年12月01日, 10.1248/jhs.49.520, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=24744469419&origin=inward
    概要:From the viewpoints of decreasing environmental burdens and recycling of materials, the adsorption ability of charcoal from coffee grounds for acidic dye (acid orange 7) removal was investigated by the batch method. Differences in the removal ratio and removal rate of acid orange 7 could be explained by differences in the properties of charcoal such as specific surface area and pore volume. In the relationship between the amount of acid orange 7 adsorbed at each elapsed time and the square root of elapsed time, a good linearity was recognized. Since the good linearity between the acid orange 7 adsorption and the square root of elapsed time was recognized, the intraparticle diffusion of acid orange 7 onto pores of adsorbents was identified as the rate-limiting step in the adsorption process.
  • Adsorption characteristics of bisphenol A onto carbonaceous materials produced from wood chips as organic waste, Akio Nakanishi, Motoharu Tamai, Naohito Kawasaki, Takeo Nakamura, Seiki Tanada, Journal of Colloid and Interface Science, 252, 393, 396,   2002年12月01日, 10.1006/jcis.2002.8387, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0036968022&origin=inward
    概要:Many organic by-products have been discharged by humans, and the development of technology for recycling organic by-products has attracted much interest. In this paper, the techniques for producing carbonaceous adsorbents from an organic by-product and an application to remove endocrine disruptors are described. Wood chips as an organic by-product were carbonized at 873 to 1073 K. The iodine adsorption capacity of the obtained carbonaceous materials increased with increasing carbonization temperature. The amount of bisphenol A adsorbed on the carbonized materials produced from Sugi and Hinoki at a 1073 K carbonization temperature was higher than that of activated carbon. The Freundlich constant, 1/N, of the carbonaceous materials produced from Sugi chips, Sugi sawdust, and Hinoki sawdust was similar to that of the activated carbon. This result indicated that the affinity between bisphenol A and the carbonaceous materials or the activated carbon was similar. Their Freundlich constant, K, was greater than that of the activated carbon. Hence, bisphenol A could be efficiently removed by the carbonaceous materials. © 2002 Elsevier Science (USA).
  • Adsorption of dyes onto carbonaceous materials produced from coffee grounds by microwave treatment, Mizuho Hirata, Naohito Kawasaki, Takeo Nakamura, Kazuoki Matsumoto, Mineaki Kabayama, Takamichi Tamura, Seiki Tanada, Journal of Colloid and Interface Science, 254, 1, 17, 22,   2002年10月30日, 10.1006/jcis.2002.8570, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0036399287&origin=inward
    概要:Organic wastes have been burned for reclamation. However, they have to be recycled and reused for industrial sustainable development. Carbonaceous materials were produced from coffee grounds by microwave treatment. There are many phenolic hydroxyl and carboxyl groups on the surface of carbonaceous materials. The base consumption of the carbonaceous materials was larger than that of the commercially activated carbon. The carbonaceous materials produced from coffee grounds were applied to the adsorbates for the removal of basic dyes (methylene blue and gentian violet) in wastewater. This result indicated that the adsorption of dyes depended upon the surface polar groups on the carbonaceous materials. Moreover, the Freundlich constants of isotherms for the adsorption of methylene blue and gentian violet onto the carbonaceous materials produced from coffee grounds were greater than those for adsorption onto activated carbon or ceramic activated carbon. The interaction was greatest between the surface or porosity of the carbonaceous materials and methylene blue and gentian violet. The microwave treatment would be useful for the carbonization of organic wastes to save energy. © 2002 Elsevier Science (USA).
  • Adsorption characteristics of bisphenol A onto carbonaceous materials produced from wood chips as organic waste, S. Tanada, S. Tanada, N. Kawasaki, N. Kawasaki, T. Nakamura, Journal of Colloid and Interface Science, 252, 409, 418,   2002年08月15日, 10.1006/jcis.2002.8471, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0037103905&origin=inward
    概要:A novel technique based on the zeta potential distribution measurement was developed to study the interactions between bitumen and clays in aqueous solutions. Bitumen and clay suspension exhibited a single modal zeta potential distribution. Without calcium addition, a mixture of bitumen emulsion and montmorillonite or kaolinite clay suspension showed a bimodal zeta potential distribution, indicating at most a weak attraction between the two and a marginal slime coating. Calcium addition suppressed zeta potential values substantially for all the three components examined. Bimodal zeta potential distribution remained when 1 mM calcium was added into the mixture of bitumen emulsion and kaolinite clay suspension, indicating a weak attraction between the two and hence marginal slime coating. The zeta potential distribution became of single modal when 1 mM calcium was added into a mixture of bitumen emulsion and montmorillonite clay suspension, suggesting a strong attraction between the two and hence a severe slime coating. From zeta potential measurement using single component emulsion/suspension, bitumen emulsion featured its own electrokinetics, significantly different from those for kaolinite and montmorillonite clay suspensions. The results interpreted by zeta potential distribution measurements agreed with the results from laboratory bitumen flotation data and plant experience.
  • Adsorption of hydrogen sulfide by zinc-containing activated carbon, T. Nakamura, N. Kawasaki, M. Hirata, Y. Oida, S. Tanada, Toxicological and Environmental Chemistry, 82, 93, 98,   2001年10月01日, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0035480626&origin=inward
    概要:Zinc-containing activated carbons (Zn-ACs) were prepared by impregnating raw activated carbon (R-AC) with zinc acetate solution. Then, the capacity of Zn-ACs to adsorb hydrogen sulfide as an offensive odor was evaluated. The values of physical properties of Zn-ACs were smaller than those of R-AC due to the filling pores of activated carbon by zinc acetate. However, the amounts of hydrogen sulfide adsorbed onto Zn-ACs were larger than that onto R-AC in equilibrium pressure below 100 hPa. The increase in the amount adsorbed onto Zn-ACs at the lower pressure region may be due to the chemical interaction of the zinc on the adsorbent and hydrogen sulfide.
  • Trihalomethane removal by activated carbon fiber, T. Nakamura, N. Kawasaki, M. Araki, K. Yoshimura, S. Tanada, Journal of Environmental Science and Health - Part A Toxic/Hazardous Substances and Environmental Engineering, A36, 7, 1303, 1310,   2001年09月17日, 10.1081/ESE-100104879, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0034837501&origin=inward
    概要:For the safety of drinking water, trihalomethanes are removed by adsorption onto activated carbon fiber from single-component solutions. The amounts adsorbed onto adsorbents with large surface area and/or pore volume were small. Stronger surface hydrophobicity of adsorbent was correlated with a larger amount of trihalomethanes adsorbed. A trihalomethane with bromine was adsorbed to a greater extent than that with chlorine. The differences in the amounts adsorbed among trihalomethanes can be explained by the polarity of trihalomethane molecules. The amount of trihalomethanes adsorbed was mainly dominated by the strength of hydrophobicity of activated carbon fibers.
  • Inclusion behavior of 4-nonylphenol into cyclodextrin derivatives, Naohito Kawasaki, Mamiko Araki, Takeo Nakamura, Seiki Tanada, Journal of Colloid and Interface Science, 238, 1, 215, 218,   2001年07月01日, 10.1006/jcis.2001.7517, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0035387947&origin=inward
    概要:The solubilities of 4-nonylphenol in five kinds of hydroxypropyl-cyclodextrin (HP-CDs) solutions were investigated in order to evaluate them for soil remediation. The relative aqueous-phase concentration of 4-nonylphenol linearly increased with the increasing HP-CD concentration. The addition of HP-β-CD (degree of substitution, D.S. = 0.6) produced the largest change because the inner core of HP-β-CD is the most hydrophobic. The solubility of 4-nonylphenol in the HP-CD solutions depended upon the cavity diameter and the degree of HP-CD substitution. Both ozone and activated carbon treatments have been using for removing organic compounds and foul odor compounds from tap water. As the inclusion complexes moved into the groundwater, the ozone degradation of the inclusion complexes was estimated. The 4-nonylphenol-HP-CD inclusion complexes were easily degraded by ozone. The degree of degradation increased with the increasing ozonization time. Weakly acidic compounds were produced from the 4-nonylphenol-HP-CD inclusion complexes by ozonization. HP-CDs could be used for the removal of 4-nonylphenol from soil. © 2001 Academic Press.
  • Formation of trihalomethanes from dyes by ozone treatment, S. Tanada, N. Kawasaki, T. Nakamura, M. Araki, O. Shinohara, Toxicological and Environmental Chemistry, 79, 1, 7,   2001年01月01日, 10.1080/02772240109358971, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0034993890&origin=inward
    概要:The amount of chloroform produced from dyes (orange II, methylene blue, and methylrosanilinium chloride) and humic acid by adding chlorine after the ozone treatments was investigated. Some dyes and humic acid were degraded by ozone and produced polar and acidic organic compounds. The amount of chloroform produced from orange II increased or decreased with the ozonization time, while that produced from methylene blue and humic acid decreased with ozonization time. Methylrosanilinium chloride did not produce the trihalomethane by chlorine disinfection. Thus, some but not all dyes produce trihalomethanes by ozone treatment and chlorine disinfection.
  • Removal of bisphenol A in soil by cyclodextrin derivatives, M. Araki, N. Kawasaki, T. Nakamura, S. Tanada, Toxicological and Environmental Chemistry, 79, 23, 29,   2001年01月01日, 10.1080/02772240109358973, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0034981921&origin=inward
    概要:The apparent aqueous solubility of the endocrine disruptor in hydroxypropyl-cyclodextrin (HPCD) solutions was investigated for evaluating the remediation of soil contamination and ground water pollution. The apparent solubility of bisphenol A (BPA) in water was significantly increased in HP-CD solutions. The solubilization effect of HP-CD's is caused by the formation of inclusion complexes of BPA and cyclodextrin. The relative aqueous-phase concentration of BPA linearly increased with increasing HP-CD concentration. The solubility of BPA increased in the order of the addition of HP-α-CD, HP-γ-CD, and HP-β-CD. However, it did not depend upon the degree of hydroxypropylation substitution. It is concluded that HP-CD may be utilized for the remediation of soil contamination.
  • Characteristics of cyclodextrin adsorption onto activated carbons, Ikuo Abe, Tomoko Fukuhara, Naohito Kawasaki, Mitsunori Hitomi, Yoshiya Kera, Journal of Colloid and Interface Science, 229, 2, 615, 619,   2000年09月15日, 10.1006/jcis.2000.7070, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0034665926&origin=inward
    概要:Whereas the amount of cyclodextrin (CD) adsorbed onto the large-pore activated carbon A (AC-A) increased with the number of glucose units, the amount adsorbed onto the small-pore activated carbon B (AC-B) showed the opposite tendency. This behavior can be accounted for in terms of a molecular exclusion. It is known that a good linear relationship is obtained between the Freundlich constants log K and 1/N for hydrophobic adsorption. The adsorption of CDs onto AC-A obeyed this relation, but, because of the molecular exclusion, the plots of AC-B deviated greatly. The adsorption of CDs onto AC-A was not explainable in terms of solubility. This could be because, in the case of a solid compound, adsorbability depends on the chemical potential of the molecule in aqueous solution whereas solubility depends also on the heat of fusion of the solid. In order to estimate the relative chemical potential of CDs in water, a method based on the numbers of carbon atoms and oxygen atoms in the molecule was devised which allowed a more accurate estimation of CD adsorbability than did solubility. The mean pore diameter of AC-A increased after CD adsorption, while that of AC-B showed little change. (C) 2000 Academic Press.
  • Characteristics of nonafluorobutyl methyl ether (NFE) adsorption onto activated carbon fibers and different-size-activated carbon particles, Seiki Tanada, Naohito Kawasaki, Takeo Nakamura, Mamiko Araki, Yukihiro Tachibana, Journal of Colloid and Interface Science, 228, 2, 220, 225,   2000年08月15日, 10.1006/jcis.2000.6949, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0034663966&origin=inward
    概要:The characteristics of adsorption of 1,1,1,2,2,3,3,4,4-nonafluorobutyl methyl ether (NFE), a chlorofluorocarbon (CFC) replacement, onto six different activated carbon; preparations (three activated carbon fibers and three different-sized activated carbon particles) were investigated to evaluate the interaction between activated carbon surfaces and NFE. The amount of NFE adsorbed onto the three activated carbon fibers increased with increasing specific surface area and pore volume. The amount of NFE adsorbed onto the three different-sized-activated carbon particles increased with an increase in the particle diameter of the granular activated carbon. The differential heat of the NFE adsorption onto three activated carbon fibers depended on the porosity structure of the activated carbon fibers. The adsorption rate of NFE was also investigated in order to evaluate the efficiency of NFE recovery by the activated carbon surface. The Sameshima equation was used to obtain the isotherms of NFE adsorption onto the activated carbon fibers and different-sized-activated carbon particles. The rate constant k for NFE adsorption onto activated carbon fibers was larger for increased specific surface area and pore volume. The rate of NFE adsorption on activated carbons of three different particle sizes decreased with increasing particle diameter at a low initial pressure. The adsorption isotherms of NFE for the six activated carbons conformed to the Dubinin-Radushkevich equation; the constants BE0 (the affinity between adsorbate and adsorbent) and W0 (the adsorption capacity) were calculated. These results indicated that the interaction between the activated carbon and NFE was larger with the smaller specific surface area of the activated carbon fibers and with the smaller particle diameter of the different-sized-activated carbon particles. The degree of packing of NFE in the pores of the activated carbon fibers was greater than that in the pores of the granular activated carbons. (C) 2000 Academic Press.
  • Reduction of iron(III) ion by activated carbon fiber, M. Uchida, O. Shinohara, S. Ito, N. Kawasaki, T. Nakamura, S. Tanada, Journal of Colloid and Interface Science, 224, 2, 347, 350,   2000年04月15日, 10.1006/jcis.2000.6713, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0034655239&origin=inward
    概要:The mechanisms of adsorption of iron(II) ion, iron(III) ion, and reduced iron(III) ion onto an activated carbon fiber and the ability of carbon fibers to reduce iron(III) ion were investigated on the basis of the amounts of iron ion adsorbed. The amount of iron(II) ion adsorbed onto the activated carbon fiber increased with increasing adsorption temperature. Iron(II) ion was more easily removed by the activated carbon fiber than iron(III) ion. Iron(III) ion was adsorbed onto the activated carbon fiber after being reduced to iron(II) ion. The reduction ability of A-20 was stronger than that of A-10 because the hydrophilic groups of A-20 were larger than those of A-10. It is concluded that the activated carbon fiber has a reduction effect on iron(III) ion and that the reduction effect of the activated carbon fiber depended on the number of hydrophilic groups on the activated carbon fiber.

  • Advanced adsorption of humic acid for trihalomethanes control, Masahiro Uchida, Seishiro Ito, Seiki Tanada, Naohito Kawasaki, Takeo Nakamura, Journal of Environmental Science and Health - Part A Toxic/Hazardous Substances and Environmental Engineering, 35, 2, 245, 251,   2000年02月01日, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0034142149&origin=inward
    概要:For advanced trihalomethanes control, the removal of humic acid, which is one of trihalomethanes precursors, was investigated. The smaller the particle size of activated carbon, the more humic acid was adsorbed. It will be presumed that the contact surface area dominates the amount of humic acid adsorbed. Moreover, the humic acid solution was treated with ozone, and the adsorption removal by activated carbon was investigated. The amount of humic acid adsorbed increased with ozonization time. It is assumed that degradation to lower molecular weight fragments by ozonolysis contributed to the increase in the amount adsorbed onto activated carbon. It was concluded that preozonation was effective in removing humic acid.
  • Relationship between surface-modified activated carbons and volatile chlorinated hydrocarbons, O. Shinohara, N. Kawasaki, T. Nakamura, M. Araki, S.

    概要:The interactions between surface-modified activated carbons and trichloroethylene (TCE) or tetrachloroethylene (PCE) were estimated based on the adsorption isotherms and constants of the Freundlich and Langmuir equations. This result indicated that PCE strongly interacts with the activated carbon surface compared to TCE, because PCE is a more hydrophobic compound than TCE. The adsorption of TCE onto the activated carbon was effected to the presence of water, while that for PCE was not. The removal of TCE has to use for more hydrophobic activated carbon, that is, the activated carbon treated with hydrogen gas (AC-Red). On the other hand, the removal of PCE in water could be removed by the untreated activated carbon (AC). | The interactions between surface-modified activated carbons and trichloroethylene (TCE) or tetrachloroethylene (PCE) were estimated based on the adsorption isotherms and constants of the Freundlich and Langmuir equations.

  • Competitive adsorption of chloroform and iron ion onto activated carbon fiber, M. Uchida, S. Ito, N. Kawasaki, T. Nakamura, S. Tanada, Journal of Colloid and Interface Science, 220, 2, 406, 409,   1999年12月15日, 10.1006/jcis.1999.6519, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0033572209&origin=inward
    概要:Chloroform in tap water has been a significant problem because it may be a carcinogenic substituent. Iron ion exists in tap water because of dissolution from iron water pipes. Iron ions in tap water cause discoloration and a bad odor. The isotherms of chloroform and iron ion adsorption onto activated carbon fibers in a single solution (chloroform or iron ion) and in a binary mixture solution (chloroform and iron ion) were investigated to estimate the competitiveness between chloroform and iron ions. The amount of adsorbed iron ions increased with increasing pore volume of the activated carbon fibers, while that of chloroform decreased. The amount of chloroform adsorbed onto the activated carbon fibers in the binary mixture solution was greater than that in the single solution. These results indicate that the adsorption of chloroform and iron ion onto activated carbon fibers could be competitive.
  • Formation of trihalomethanes from humic acid by ozone and activated carbon fibers treatments, Masahiro Uchida, Seishiro Ito, Seiki Tanada, Naohito Kawasaki, Takeo Nakamura, Toxicological and Environmental Chemistry, 72, 245, 252,   1999年12月01日, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0033496143&origin=inward
    概要:Humic acid, which is a trihalomethane precursor, was produced by the putrefaction of withered leaves. Trihalomethanes are produced by chlorine disinfection when tap water is treated with ozone and activated carbon in a purification plant. The amount of chloroform produced from humic acid by adding chlorine after the ozone and activated carbon fiber treatments was investigated. Humic acid was degraded by ozone to polar and acidic organic compounds by the addition of hypochlorite. The amount of chloroform produced increased with increasing treatment temperature, while it decreased with increasing ozonization time. It was also lowered by the addition of activated carbon fibers after the ozonization.
  • Recovery efficiency of the hydrofluorocarbon (HFC-134a) by activated carbons of different physicochemical properties, Naohito Kawasaki, Seiki Tanada, Takeo Nakamura, Takashi Ohue, Ikuo Abe, Toxicological and Environmental Chemistry, 69, 3/4, 449, 458,   1999年12月01日, 10.1080/02772249909358724, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0008474849&origin=inward
    概要:The adsorption characteristics of 1,1,1,2-tetrafluoroethane (HFC-134a) on activated carbon were investigated to evaluate the recovery efficiency of HFC-134a by six activated carbons (two granular activated carbons (GAC1 and GAC2), one high-surface area activated carbon (HAC), and three activated carbon fibers (ACF10, ACF15, and ACF20)). HFC-134a adsorption on the activated carbons increased with increase in the specific surface area and pore volume of the activated carbon. The differential heat of the HFC-134a adsorption decreased with increase in the percentage of the micropore volume to the total pore volume. The adsorption model of HFC-134a on the activated carbon could be based on the Langmuir model. The constant a of the Langmuir plot of HAC and ACF20 is smaller than GAC1 or GAC2 and ACF10 or ACF15, respectively. The constant Ws of HAC has the largest value. The constant a was correlated to the heat of adsorption. It is concluded that the largest amount of HFC-134a was adsorbed on HAC, and the least amount of interaction occurred between HFC-134a and the HAC. The amount of HFC-134a adsorbed on the activated carbons over time was applied to the Sameshima equation. The adsorption rate constant of HFC-134a on HAC was the largest. The HAC could be suitable for the recovery of HFC-134a. © 1999 OPA (Overseas Publishers Association) N.V. Published by license under the Gordon and Breach Science Publishers imprint.
  • Removal of aromatic hydrocarbon compounds by hydroxypropyl-cyclodextrin, Seiki Tanada, Takeo Nakamura, Naohito Kawasaki, Yasuhiro Torii, Shinzo Kitayama, Journal of Colloid and Interface Science, 217, 2, 417, 419,   1999年09月15日, 10.1006/jcis.1999.6350, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0033567467&origin=inward
    概要:Activated carbon has been used for the recovery and removal of benzene, toluene, and xylenes in air and water for a long time. However, removal of benzene, toluene, and xylenes from soil is very difficult. They can be removed by an increase in the apparent solubility of organic compounds in soil. The apparent solubilities of benzene, toluene, and xylene were investigated to estimate their inclusion behavior into natural cyclodextrins (CDs) and hydroxypropyl-cyclodextrins (HP-CDs) in the liquid phase. The apparent solubilities of benzene, toluene, and xylenes did not increase by adding natural CDs but did increase when HP-CDs were added. Benzene, toluene, and xylenes in a HP-CD solution depended on the relationship between the molecular diameter of benzene, toluene, and xylenes, the CD cavity size, and the 1-octanol-water partition coefficient. That of p-xylene was larger than that of o-xylene and m-xylene because of the smallest steric hindrance of p- xylene.

    概要:Formaldehyde has been used for disinfection and antisepsis in hospitals due to its bactericidal action, but it is toxic to humans. Hence, we developed adsorbates for the removal of formaldehyde. The adsorbate was prepared by the amination of an activated carbon surface. The removal efficiency and the adsorption mechanism of formaldehyde onto the aminated activated carbon were studied. The concentrated sulfuric acid and nitric acid treatment introduced nitro groups onto the surface of the activated carbon. The nitro groups were reduced by the reaction of powdered iron and hydrochloric acid to the amino groups. The amount of formaldehyde adsorbed onto the activated carbon increased with the amination of the activated carbon because of the increasing interaction between the surface of the activated carbon and the formaldehyde.
  • Adsorption removal of paraquat and diquat onto activated carbon at different adsorption temperature, T. Nakamura, N. Kawasaki, H. Ogawa, S. Tanada, M. Kogirima, M. Imaki, Toxicological and Environmental Chemistry, 70, 275, 280,   1999年01月01日, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0032789307&origin=inward
    概要:The efficacy of activated carbon as an oral adsorbent in removing paraquat and diquat from purified water and physiological saline solution at different temperatures was investigated for the primary treatment of acute poisoning. The amounts of paraquat and diquat adsorbed onto activated carbon were large in low temperature condition. The adsorption mode of paraquat and diquat onto activated carbon was mainly physical adsorption. It was recognized that the high adsorption ratio of paraquat and diquat onto activated carbon was obtained by the administration of low temperature suspended solution which was a mixture of activated carbon and gastrointestinal lavage detergent.
  • Recovery of seven kinds of CFC and CFC replacements on high-surface area activated carbon, Seiki Tanada, Naohito Kawasaki, Takeo Nakamura, Ikuo Abe, Toxicological and Environmental Chemistry, 70, 483, 490,   1999年01月01日, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0032802474&origin=inward
    概要:The adsorption isotherms, the constants of the Dubinin-Radushkevich plots, and the constants of the Langmuir plots of chlorofluorocarbon (CFC) and CFC replacements on high-surface area activated carbon were investigated to estimate the recovery efficiency of CFC and CFC replacements. The adsorption and desorption of HFC134a on a high-surface area activated carbon was much easier than that of CFC113 and the CFC replacements. The recovery efficiency of CFC replacements depends on the hydrogen atoms in molecule. It is possible that the saturated amount adsorbed in the pores or on the surface of the activated carbon could be evaluated by the W(s) constant of the the Langmuir equation and the W(o) constant of the Dubinin-Radushkevich equation. The a constant of the Langmuir equation and the BE(o) constant of the Dubinin-Radushkevich equation depend on the molecular composition.

    概要:Experimentally measured water vapor sorption isotherms (SIe) of alkaliprocessed collagen fibers C-20 and C-30 were compared with the theoretical isotherms (SIt) to elucidate the change of the microporous structure caused by the alkali-treatment during 20 and 30 d. The amino acid compositions of the collagen fibers were analyzed, then SIts were calculated from multiplying the degree of hydrophilicity of the sorption site. The amounts of sorbed water of SIe were greater than those of SIt in the range of the water activity higher than 13%. The great difference was observed at C-20 rather than C-30. The difference between SIe and SIt was attributed to the large amount of sorbed water in the micropores. This result confirms that the change of collagen fiber during alkali process is explained by the microporous structure, not by the stability of the triple-helix structure.

    概要:2,2,3,3,3-Pentafluoro-1-propanol (5FP) has been considered a viable CFC replacement compound. However, 5FP must be recovered in order to decrease the environmental impact and save energy. Activated carbons have been used for the recovery and removal of organic solvents. From the point of view of 'zero emission,' 5FP and activated carbon must be completely recycled. The purpose of this study is to recycle the activated carbons and to increase the recovery efficiency of 5FP using the activated carbons (ST-ACs) which were coated with tetraethoxysilane by the sol-gel method. The amount of 5FP adsorbed onto the ST-ACs and the degree of 5FP decomposition by the ST-ACs were measured in order to estimate the relationship between the ST-AC surface and 5FP. The amount of 5FP adsorbed and the degree of 5FP decomposition indicated that the recovery of 5FP is suitable for the use with the ST-ACs.

  • Adsorbability of 1,1,1,2-tetrafluoromethane (HFG134a) onto plasma-treated activated carbon in CF4 and CCl4, Seiki Tanada, Naohito Kawasaki, Takeo Nakamura, Takashi Ohue, Ikuo Abe, Journal of Colloid and Interface Science, 191, 2, 337, 340,   1997年07月15日, 10.1006/jcis.1997.4965, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0031571151&origin=inward
    概要:The adsorbability of 1,1,1,2-tetrafluoroethane (HFC134a), which has been the CFC12 replacement, onto tetrafluoromethane and tetrachloromethane plasma-treated activated carbon(FT-ACs and CT-ACs) was investigated. It is proved that the fluorine and the chlorine, which were produced by plasma treatment, were introduced into the pores having radii greater 7.5 Å and with less than 7.5 Å by plasma treatment, respectively. The adsorption site of HFC134a onto activated carbon may change with the quantities of fluorine or chlorine on the surface of the activated carbon. The amount of HFC134a adsorbed per unit specific surface area of FT-ACs and CT-ACs slightly increased a little compared to the untreated activated carbon (U-AC). The amount of fluoride ion eluted before the adsorption of HFC134a from the FT-ACs increased with the increasing plasma treatment time. That after the adsorption of HFC134a from only the activated carbon with the shortest plasma treatment time decreased. The amount of chloride ion eluted before the adsorption of HFC134a from the CT-ACs increased after 15 min of plasma treatment, but decreased with 30 min of plasma treatment. The chloride ion amount from the CT-ACs decreased after the adsorption of HCF134a. These results could be explained by the Langmuir constants a and Ws, which represent the adsorption equilibrium constant and the saturated amount of HFC134a adsorbed, respectively. The ratio of fluorine and chlorine species, the adsorption type, the layer interstitial type, and the covalent type, is different based on the plasma treatment time. It is concluded that the amount of HFC134a adsorbed onto the FT-ACs and CT-ACs did not depend upon the change of pore structure by the fluorine and chlorine.

    概要:The ozone degradation of fluorine was investigated using the tetrafluoromethane plasma-treated activated carbon (PT-AC). The ozone in the stratosphere has been degraded by the chloride and bromide radicals which are produced from chlorofluorocarbons and bromofluorocarbons, respectively. However, we believe that fluorine also was related to the ozone degradation. The fluoride was introduced onto the activated carbon surface by tetrafluoromethane plasma treatment. The breakthrough curve of ozone onto PT-AC was measured to elucidate the relationship between the ozone and the fluoride. The amount of ozone adsorbed/degraded onto the PT-AC was larger than the amount that was adsorbed/degraded onto the untreated activated carbon. The amount of fluoride ion eluted from the PT-AC before the adsorption/degradation of ozone was larger than that which eluted after the adsorption/degradation of ozone. These results indicated that the ozone was degraded by the fluoride on the PT-AC surface.

    概要:Chloroform as a carcinogen removal by surface modified activated carbon from an aqueous solution was investigated for the assurance of safe water. Surface hydrophobilized activated carbon by hydrogen gas adsorbed the largest amount of chloroform. To elucidate the dominant factor of adsorption removal of chloroform, correlations between the amount adsorbed and physicochemical properties of adsorbents. A significant inverse correlation was recognized between the amount of chloroform adsorbed and the base consumption. It was found that the existence of acidic groups on the surface of activated carbon inhibits the adsorption of chloroform. It was concluded that the suitable adsorbent for chloroform removal was an activated carbon with more hydrophobic surface.

    概要:有機性廃棄物のリサイクル手法として炭化過程は簡易で安価な手法である。特に有機性廃棄物中, 最も多く産出される廃木材は炭化を通して, 有用な木炭としてリサイクル利用が期待される。日本は湿気が多く過去, 床下調湿剤として木炭が広く使用されてきた。しかし, 木炭は調湿性能が一般的に低く, 調湿材として利用する場合, 大量の木炭を要する。本研究では, 高調湿能付加木炭・鉄複合材料の創製を指向し, 鉄の酸化過程を用いて木炭表面を鉄で修飾することで, 木炭よりも省スペースかつ高性能な調湿材料, 木炭・鉄複合材料 (Ch-Fe) を製造した。Ch-Feの調湿性能は最高で従来の木炭の約4倍以上を示し, 特に調湿材として最も性能が要求される高湿度領域 (相対湿度0.55以上) における調湿性能が向上された。現代社会において重要な問題の一つである有機性廃棄物のリサイクルおよび地球温暖化防止という視点から, Ch-Feは高性能な調湿材として有益な再資源化方法となりうることが示唆された。

    概要:Recently, formaldehyde liberated from wallpapers, furnitures and adhesive agents in new buildings and houses cause troubles in human health, and this is called the sick building symdrome. In this study, the carbonaceous materials are prepared from coffee grounds by microwave treatment or by surface-treatments with two different silane coupling agents. We estimated the removal efficiency of formaldehyde by such materials. The water contents of coffee grounds are larger than those of other wastes and thus they were easily carbonized. Both the amount of formaldehyde adsorbed onto the carbonaceous materials and the adsorption rate increased with increasing microwave treatment period, and increased with increasing concentration of silane coupling agents, because the numbers of amino groups on the carbonaceous materials increase. The carbonaceous materials prepared from the coffee grounds would be utilized for adsorbates to remove formaldehyde.

    概要:Recently, some harmful compounds and bacteria have been detected from tap water. Particularly, the nitrite nitrogen causes methemoglobinemia and cyanosis for infants. In this study, the surfaces of coffee grounds were carbonized by microwave and carbonaceous materials were produced. The specific surface area of the coffee grounds did not change by carbonization, while the base consumption decreased. Moreover, we estimated the extent of the adsorption of nitrite nitrogen onto the coffee grounds in terms of its removal from tap water. The adsorption mechanism of nitrite nitrogen onto coffee grounds would be monolayer adsorption, because the adsorption isotherms fitted to Freundlich or Langmuir equations. It is suggested that the adsorption of nitrite nitrogen onto coffee grounds is related to the phenolic hydroxyl and carboxyl groups. The coffee grounds thus can be utilized for the removal nitrite nitrogen from tap water.

    概要:本研究は,コーヒー豆かすの再資源化を目的として,コーヒー豆かすの表面をCaCl2により処理し,それらへのNO3−-NおよびNO2−-Nの吸着機構について検討した.その結果,600°Cで炭化処理したコーヒー豆かす炭(CG600)へのNO3−-NおよびNO2−-Nの吸着量は,他の温度で炭化処理したものに比べ,最も高い吸着量を示した.また,吸着時の温度が高いほど増大が認められ,吸着開始24 hで平衡に達した.一方,NO3−-NおよびNO2−-Nの吸着によりコーヒー豆かす炭から塩化物イオンが溶出した.また,吸着等温線はFreundlich式およびLangmuir式に適合した.したがって,CG600表面に賦与された塩素はNO3−-NおよびNO2−-Nとイオン交換していることが示唆された.これらのことから,コーヒー豆かすは,CaCl2水溶液で処理することにより再資源化され,NO3−-NおよびNO2−-Nの除去能を有することがわかった.

    概要:3価ヒ素および6価クロムはヒトの健康に対し悪影響をおよぼすことで広く知られている.これらを除去するため,エチルセルロースおよびアルミナゾル520の2種類の結合剤を用いギブサイト(GB)の造粒を行い,吸着能について検討した.2種類の造粒GBは3価ヒ素および6価クロム吸着能を示し,3価ヒ素に比べ6価クロムの吸着能が高いことがわかった.しかし,エチルセルロースによる造粒は,アルミナゾル520による造粒とは異なり,溶媒を必要とするため製造工程が煩雑になり,経済性もはるかに劣る.造粒GBはGBに比べ3価ヒ素および6価クロムともに吸着量は減少したが,フィールドで適用できるものと考えられる.2成分系での3価ヒ素の吸着量は単成分系に比べ増加し,6価クロムの吸着量は大きな差は認められなかった.このことは,GBの表面極性と3価ヒ素および6価クロムとの親和性やGBの細孔が要因であると考えられる.

    概要:通常、雑音中に含まれる所望の信号を抽出する場合、LMS等のアルゴリズムを用いて雑音抑制が行われている。しかしながら、実際の雑音環境下ではトレーニング信号を作成できない場合があり、この手法は常に有効であるとは限らない。そこで、近年ブラインド方式による信号分離が盛んに研究されており、そのアルゴリズムも数多く報告されている。しかしながら、現在提案されているアルゴリズムの多くは、ダイレクトパスに零点が存在する場合、システムが不安定になるという問題がある。本論文では、2入力2出力システムにおける信号分離アルゴリズムを提案する。本アルゴリズムは、ダイレクトパスおよびクロストークパスを三角関数を用いて表現しており、ダイレクトパスが零点を含む場合にも信号分離が可能である。

    概要:食生活の欧米化に伴う慢性疾患への罹患およびそれらの疾患による死亡が懸念されている中にあった、伝統的な米飯を主体とする日本食が疾病予防の観点から注目されている。本研究においては、調理用水の水質、特に硬度の異なる水を用いて炊飯した米飯の食味(におい、かたさ、色つや、味、総合)について、19〜20才の女子学生をパネラーとして食味試験を行った。かたさ、色つや以外の食味試験項目については、比較的硬度の高い水で炊飯した米飯ほど、統計的に有意な高い評価点を示した。また硬度の高い水ほど、60℃および65℃における米に対する吸水率において大きな差が認められた。これらの結果より、炊飯米にカルシウム、マグネシウムといったミネラル成分を補充することにより、食味を向上させ、また慢性疾患の予防にもつながるであろうことが期待される。

  • Water sorption characteristics based on amino acid compositions of alkali-processed collagen fiber, Keito Boki, Naohito Kawasaki, Hitoshi Takahashi, Kazuo Minami, Yakugaku Zasshi, 117, 4, 248, 254,   1997年04月01日, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0030922342&origin=inward
    概要:Experimentally measured water vapor sorption isotherms (SIe) of alkali- processed collagen fibers C-20 and C-30 were compared with the theoretical isotherms (SIt) to elucidate the change of the microporous structure caused by the alkali-treatment during 20 and 30 d. The amino acid compositions of the collagen fibers were analyzed, then Sits were calculated from multiplying the degree of hydrophilicity of the sorption site. The amounts of sorbed water of SIe were greater than those of Sit in the range of the water activity higher than 13%. The great difference was observed at C-20 rather than C-30. The difference between SIe and SIt was attributed to the large amount of sorbed water in the micropores. This result confirms that the change of collagen fiber during alkali process is explained by the microporous structure, not by the stability of the triple-helix structure.
  • Inclusion of volatile organic compounds into natural cyclodextrins and their branched cyclodextrins in the gaseous phase, Seiki Tanada, Takeo Nakamura, Naohito Kawasaki, Sinzo Kitayama, Yoshiyuki Takebe, Journal of Colloid and Interface Science, 186, 1, 180, 184,   1997年02月01日, 10.1006/jcis.1996.4627, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0031075429&origin=inward
    概要:The adsorption isotherms of water, the differential heat of adsorption, and the entropy of adsorbed water were investigated to elucidate the structure of stability of cyclodextrins (CyD) and branched CyD's. The amount adsorbed on branched CyD's increased with increasing relative humidity. The steep rise in the amount adsorbed at higher relative humidities indicated that the structure of branched CyD's was affected by the water molecules at these higher relative humidities. The bonding force between α-CyD's and water molecules was stronger than that between their branched CyD's and water, while that between β-CyD's and water was weaker than that between their branched CyD's and water. We have used activated carbons for the recovery of organic solvents. There are polar groups on the activated carbon surface. Therefore, the recovered organic solvents were degraded by these groups. However, such polar groups are not expected for the hydroxyl groups of the CyD's. The amounts of 1,1,1-trichloroethane, benzene, and toluene included in natural CyD's and their branched CyD's were measured. The amounts of organic solvents included in the CyD's depended upon the cavity radii and the glucosyl and maltosyl functional groups of the CyD's and the radii of the organic solvent molecules.
  • Adsorption of inhalational anesthetics and hydrochlorofluorocarbons on activated carbons as a biological model, Seiki Tanada, Naohito Kawasaki, Takeo Nakamura, Ikuo Abe, Chemical and Pharmaceutical Bulletin, 45, 2, 231, 235,   1997年01月01日, 10.1248/cpb.45.231, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0030951778&origin=inward
    概要:Chlorofluorocarbon (CFC) replacements have recently been used for their lower stability and because they have carbon-hydrogen bonds, which means that their atmospheric lifetime is expected to be much shorter than those of CFCs. The adsorption properties of 1,1,2-trichloro-1,2,2-trifluoroethane (CFC113) and its replacement compounds, 1,1-dichloro-2,2,2-trifluoroethane (HCFC123), 1,1-dichloro-1-fluoroethane (HCFC141b), and 1,1-dichloro-1,2,2,3,3- pentafluoropropane (HCFC225ca) on four kinds of activated carbons were investigated. The amount of CFC and HCFCs adsorbed on the activated carbon was concluded to depend upon the number of chloride and carbon atoms in their molecules. The adsorption isotherms of inhalational anesthetics (halothane, chloroform, enflurane, isoflurane, and methoxyflurane) on the activated carbon were measured to evaluate the action mechanism of inhalational anesthesia. The adsorption isotherms of CFC, HCFC, and the inhalational anesthetics were fitted to the Freundlich equation. The Freundlich constant N was well correlated with the minimum alveolar concentration (MAC) of the inhalational anesthetic: 1 MAC means that 50% of the patients will not move during a surgical operation. The adsorption mechanism of inhalational anesthetics on the surface of the activated carbon is concluded to be similar to the adsorption mechanism on a nerve cell. The anesthesia of CFC replacements can be estimated by the Freundlich constant N of the adsorption isotherms.
  • Adsorption removal of chloroform and bromoform by activated carbon fiber, Masahiro Uchida, Takeo Nakamura, Naohito Kawasaki, Shinzo Kitayama, Seiki Tanada, Toxicological and Environmental Chemistry, 63, 1/4, 227, 231,   1997年01月01日, 10.1080/02772249709358532, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0030663803&origin=inward
    概要:Adsorption characteristics of chloroform and bromoform onto activated carbon fibers (ACFs) for the safety drinking water were investigated. The amounts of chloroform and bromoform adsorbed onto ACFs decreased with their grade number that is the surface area and pore volume. Bromoform was more easily adsorbed onto ACFs than chloroform due to the difference in water solubility. The dominant factor of chloroform and bromoform adsorption onto ACFs may be the surface hydrophobicity of adsorbent rather than the surface area or pore volume.

    概要:Chloroform removal by activated carbon with a view to elucidating the dominant factor was investigated for the assurance of safe water. A significant correlation was recognized between the amount of chloroform adsorbed and the amount of water adsorbed as the indicator of surface hydrophobicity of adsorbent. No significant correlations were recognized between the amount of chloroform adsorbed and the surface area, pore volume or surface pH. It was concluded that a dominant factor of chloroform adsorption by activated carbon was the degree of surface hydrophobicity of adsorbent.

  • Effect of activated carbon fibers with different physicochemical properties on the adsorption rate of volatile chlorinated hydrocarbons, S. Tanada, Y. Torii, T. Nakamura, N. Kawasaki, S.

    概要:The adsorption rate of volatile chlorinated hydrocarbons (TCE; trichloroethylene, PCE; tetrachloroethylene, MC; 1,1,1-trichloroethane) onto six kinds of activated carbon fibers (ACFs) was investigated. The specific surface area and the total pore volume of the ACFs became larger with an increase in the grade number. The Sameshima equation fit the adsorption isotherms and a correlation exists between the initial adsorption rate constant, k, for TCE and PCE versus the specific surface area. The mean values of the constant k increased in the order of MC, TCE. and PCE. The adsorption rate of TCE, PCE, and MC in the gaseous phase was influenced by the pore structure of the ACFs and the adsorption mechanism of TCE and PCE was almost determined by the pore packing, while that of MC cannot be explained by physicochemical properties of the ACFs alone.

    概要:Activated carbon modified by impregnation with iron (III) chloride solution (Fe-ACs) were studied to try to raise their adsorption capacity for hydrogen sulfide, a malodorous substance. The surface area and pore volume of activated carbon were decreased by impregnation, but the amount of hydrogen sulfide adsorbed onto Fe-AC was larger than that onto raw activated carbon (R-AC). In particular, a large increase of the amount adsorbed onto Fe-AC was noted at low equilibrium pressure. It was assumed that the increase of amount of hydrogen sulfide adsorbed onto Fe-AC was due to the chemical interaction between iron (III) chloride on the pores in addition to the physical adsorption onto pores of activated carbon. Fe-AC shows a high selectivity for hydrogen sulfide.
  • Adsorption properties of CFC and CFC replacements on activated carbon containing introduced ionic fluoride and chloride, Seiki Tanada, Naohito Kawasaki, Takeo Nakamura, Ikuo Abe, Journal of Colloid and Interface Science, 183, 1, 143, 147,   1996年10月15日, 10.1006/jcis.1996.0528, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0030588173&origin=inward
    概要:Plasma technology has been available for the chlorofluorocarbon (CFC) decomposition or etching of silicone. The adsorption properties of CFC (CFC113) and CFC replacements (HCFC141b, HCFC225cb, and 5FP) on several kinds of plasma-treated activated carbons (P-ACs) prepared under different treatment gases were investigated using the adsorption isotherms, the limiting pore volume (W(o)) and the affinity coefficient and energy of adsorption (BE(o)) calculated by the Dubinin-Radushkevich plot, and the quality and kinds of introduced fluoride and chloride. The dissolved fluoride and chloride atoms were introduced to the surface of activated carbon by CFC113, HCFC141b, and HCFC225cb, while the dissolved fluoride atoms were those from 5FP and tetrafluoromethane. The adsorbed amount of CFC and CFC replacements, except for 5FP, on P-ACs was larger than that on U-AC. The specific adsorption site on plasma-treated activated carbon of the CFC and CFC replacements was the fluoride atoms which were introduced by plasma treatment. It is concluded that the plasma-treated activated carbon was suitable for the recovery of CFC and CFC replacements, because the adsorbed amount of CFC and CFC replacements was larger than that on untreated activated carbon, and the adsorbed CFC and CFC replacements on activated carbon were decomposed by the plasma treatment.

  • Adsorption behavior of water molecules onto α-, β-, and γ-cyclodextrins and branched α-cyclodextrins, Seiki Tanada, Takeo Nakamura, Naohito Kawasaki, Takayuki Kurihara, Yukihiro Umemoto, Journal of Colloid and Interface Science, 181, 1, 326, 330,   1996年07月15日, 10.1006/jcis.1996.0385, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0030586377&origin=inward
    概要:Moisture adsorption properties of α-, β-, and γ-cyclodextrin (CD) and branched α-CDs were investigated to elucidate the basis of the results of adsorption isotherms of water at 10, 20, and 30°C, the differential heat of adsorption, the entropy of the adsorbed water, and the heat of immersion in water. It is concluded that the water molecules were adsorbed on the hydroxyl groups of the glucose molecule of α-CD, were first adsorbed on that of β-CD and then were included in the pore structure of β-CD, and were only included in the pore structure of γ-CD. Branched α-CDs were developed and produced to increase the interaction with water molecules. However, the interaction between the branched α-CDs and the water was smaller than that between the virgin α-CD and the water. The solubility of branched α-CD required a long time because the heat of immersion was larger in the order G2-α-CD and G1-α-CD or α-CD. It is considered that the side chain, glucosyl and maltosyl groups, decreased the interaction between the water molecule and the surface of the CD because of steric hindrance. Therefore, it is concluded that the side chain inhibited the water adsorption of the inner molecule of CD.

  • Decomposition degree of chlorofluorocarbon (CFC) and CFC replacements during recovery with surface-modified activated carbon, Seiki Tanada, Naohito Kawasaki, Takeo Nakamura, Ikuo Abe, Journal of Colloid and Interface Science, 177, 2, 329, 334,   1996年02月10日, 10.1006/jcis.1996.0039, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0029969935&origin=inward
    概要:The recovery efficiency of 1,1,2-trichloro-1,2,2-trifluoroethane (CFC113) and three CFC replacements (1,1-dichloro-1-fluoroethane, HCFC141b; 1,3-dichloro-1,1,2,2,3-pentafluoro-propane, HCFC225cb; and 2,2,3,3,3-pentafluoro-1-propanol, 5FP) were investigated on the basis of their degree of decomposition and adsorption isotherms. We prepared activated carbons with various surface polarities to elucidate the recovery efficiency, the amount adsorbed, and the degree of decomposition. A correlation between the physicochemical properties of the activated carbon surface and the amount of CFC or CFC replacements adsorbed was not observed. The amount of CFC113 adsorbed onto untreated activated carbon was the largest of all. That of HCFC225cb adsorbed onto activated carbon treated with hydrogen gas was larger than that adsorbed onto untreated activated carbon and activated carbon treated with 6 N nitric acid. The amount of 5FP and HCFC141b adsorbed on the various activated carbons was not substantial. The degree of decomposition of CFC replacements using the untreated activated carbon except for HCFC225cb was the largest of all. In the case without the activated carbon, that of CFC and the CFC replacements increased in the order 5FP, CFC113 or HCFC225cb, and HCFC141b. These results indicated that the stability of CFC and CFC replacements molecules was controlled by the number of carbon-fluoride groups and/or hydrogen atoms. It is concluded that the recovery of CFC replacements was possible using the surface-modified activated carbons rather than the untreated activated carbon. The degree of decomposition of the CFC replacements during recovery using the activated carbon depends on the relationship between the adsorption site of the surface of the activated carbon and the polarity, hydrophilic site, or hydrophobic site of the CFC replacement molecule. It is assumed that the recovery of CFC replacements using HT-AC decreased the amount of hydrofluoric acid produced.
  • Adsorption characteristics of diquat onto activated carbon from saline solution, T. Nakamura, N. Kawasaki, S. Tanada, H. Kondo, M. Imaki, Toxicological and Environmental Chemistry, 53, 153, 158,   1996年01月01日, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=5744253550&origin=inward
    概要:For the effective use of activated carbon as an antidote in acute diquat poisoning, the adsorption characteristics of diquat onto activated carbon from saline solution were investigated. The amount of diquat adsorbed onto activated carbon was increased with the increase of sodium chloride concentration in diquat solution. The rate of diquat removal by activated carbon from saline solution was also accelerated with the increase of sodium chloride concentration. These results suggest that the enhanced adsorptivity for diquat is due to the strengthening of electrostatic interaction between the surface of activated carbon and diquat with the increase of sodium chloride concentration in solution.

    概要:The adsorption characteristics of trichloroethylene (TCE), a major volatile chlorinated hydrocarbon, onto 16 kinds of granular activated carbons (GACs) in gaseous phase were investigated.The amount of TCE adsorbed on GACs was proportional to the pore volume, and the adsorption was recognized to be a physical one.Applying the Dubinin-Radushkevich (D-R) eqation to the adsorption isotherms of TCE, GACs could be classified into two types : the D-R plot was either a straight line or not depending on pore size distribution. TCE was believed to be adsorbed not only into micropores but also into transitionalpores.
  • Change in the Porous Structure of Collagen Fibers Prepared in Acidic pH Solution, Keito Boki, Naohito Kawasaki, Takamichi Tamura, Journal of Colloid And Interface Science, 173, 1, 249, 250,   1995年07月01日, 10.1006/jcis.1995.1321, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0007754061&origin=inward
    概要:Pore size distributions of acid collagen fibers were calculated by the micropore method and the Dollimore-Heal method from the adsorption isotherm of nitrogen in order to elucidate the change in pore volume through acidifying the alkali-processed collagen fiber. The micropores with radii of 12 Å or larger appeared after acidifying the raw collagen fiber C-0 with pore radii larger than 20 Å. Increases in pore volume were greater within radii of 12-15.5 or 15.5-24.5 Å rather than within radii of 24.5-95 Å. It was suggested that the interspaces of the triple helix or microfibril within the raw collagen fiber or alkali-processed collagen fibers were increased due to the formation of carboxylic acid moieties during acid preparation. © 1995 Academic Press.

    概要:Moisture sorption properties of gelatin powder and collagen fibers were investigated on the basis of the moisture sorption isotherm, the differential heat of moisture sorption, the decrease in entropy of moisture sorption and the parameter constants of the applicable isotherm equation. The amount of moisture sorbed on collagen fibers was larger than that on gelatin powder. The water molecules were absorbed on gelatin itself rather than on the active sites of gelatin. They were adsorbed on the polar groups of constitutive amino acids at amounts of moisture sorbed up to one or two monolayers and then were absorbed into collagen fibers at higher monolayers. They were kept loosely in gelatin and tightly in collagen. The structural stability of collagen to moisture was higher than that of gelatin.
  • The Recovery of Chlorofluorocarbons and Chlorofluorocarbon Replacements by Surface Modified Activated Carbon, Naohito Kawasaki, Seiki Tanada, Takeo Nakamura, Ikuo Abe, Journal of Colloid And Interface Science, 172, 2, 368, 373,   1995年06月15日, 10.1006/jcis.1995.1266, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0001514846&origin=inward
    概要:The adsorption properties of chlorofluorocarbon CFCII3 and CFC replacements (HCFC225cb and 5FP) on activated carbon treated with 6 N nitric acid or hydrogen gas were investigated on the basis of their physicochemical adsorption isotherm and Dubinin-Rudshkevich plot to elucidate the difference between untreated activated carbon (U-AC) and surface modified activated carbon (NT-AC and HT-AC) during interaction with CFCs and CFC replacements. No correlation between the physicochemical properties of the activated carbon surface and the polarity of CFCs or CFC replacements was observed. The adsorption isotherms of CFCII3, HCFC225cb, and 5FP on U-AC, NT-AC, and HT-AC have different branch points, that is, selective adsorption (HT-AC) and nonselective adsorption (NT-AC). NT-AC is well suited for the recovery of a mixture of CFCs and CFC replacements, while HT-AC is good for a sample of CFC replacements. Studying the adsorption rate is useful for increasing the recovery efficiency. Therefore, the rate of adsorption of CFCs and CFC replacements onto surface modified activated carbon was investigated. The Sameshima equation fits the adsorption isotherms. The initial rate constants k for CFC113, HCFC225cb, and 5FP onto U-AC, HT-AC, and HT-AC, respectively, were the largest. HT-AC could be adapted for the recovery of HCFC225cb and 5FP. © 1995 Academic Press. All rights reserved.

    概要:The adsorption characteristics of trichloroethylene (TCE) on untreated activated carbon (U-AC) and plasma-treated activated carbons (PT-ACs) were investigated on the basis of adsorption isotherms, differential heat of adsorption and entropy of adsorption to elucidate the difference between the U-AC and PT-ACs interactions with TCE. Differences in the amount of TCE adsorbed between U-AC and PT-ACs seemed to be attributable to the surface properties and micropore structure of the activated carbon. The interaction of the TCE - PT-AC surface was stronger than that of the TCE - U-AC surface. The amount of TCE adsorbed and strength of the TCE - activated carbon binding for the surface of the PT-AC depended on the hydrophobicity with inner the surface area of the activated carbon, that is, the porosity due to tetrafluoromethane plasma treatment. © 1995, Taylor & Francis Group, LLC.

    概要:Nitrogen adsorption isotherms on untreated activated carbon (U-AC) and plasma-treated activated carbons (PT-ACs) with tetrafluoromethane were investigated. The pore volume was calculated using the Dollimore-Heal method from the adsorption isotherms to elucidate the relationship between plasma treatment time and porosity. The total pore volume of pores with radii less than 95 angstroms decreased with plasma treatment. However, the pore volume of pores with radii less than 7.5 angstroms was unchanged. This result was explained by the results of the C constant calculated from the BET equation. The pores with radii of 7.5 to 20.5 angstroms were particularly influenced by the plasma treatment.

    概要:Efficiencies of synthetic adsorbents and attapulgites in bleaching alkali-refined rapeseed and soybean oils ranged from 13-53% and 93-97%, respectively. The Freundlich equation was more applicable than the Langmuir equation to the experimental adsorption isotherms of β-carotene on attapulgites. Bleaching with attapulgites reduced tocopherols by 12.5-29.5% in rapeseed oil and by 18.9-44.8% in soybean oil. Cosmetic-grade attapulgite was superior to the others in bleaching efficiency, equilibrium amount adsorbed and removal of free fatty acids. © 1994 American Oil Chemists' Society.
  • Moisture Sorption Characteristics of Collagen Fibers Prepared in Different Acidic pH Solutions, Keito Boki, Naohito Kawasaki, Journal of Colloid And Interface Science, 164, 2, 364, 369,   1994年05月01日, 10.1006/jcis.1994.1178, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0028425321&origin=inward
    概要:Moisture sorption isotherms of acid collagen fibers, CSs (pH 2.3-2.9) and CWs (pH 3.7-4.2), prepared from alkali-processed collagen fibers, Cs (pH 5.4-6.2), were measured. The differences in the Cs, CSs, and CWs in moisture content, heat of moisture sorption, entropy change of moisture sorption, and parameter constant value of the Henderson and the Chung and Pfost equations were investigated. At a water activity above approximately 0.3, moisture content increased in the order CSs, CWs, and Cs. The lower order of Cs, CWs, and CSs in heat of sorption at a low moisture content indicated a decrease in linkage force strength between the water molecule and collagen because of a decrease in the change of the carboxyl group due to the preparation at lower pH. The structural stability of CSs toward moisture sorption was less than those of the Cs and CWs. © 1994 Academic Press. All rights reserved.
  • Moisture sorption of gelatin powder and collagen fibers, K. Boki, N. Kawasaki, K. Minami, Yakugaku Zasshi, 114, 704, 709,   1994年01月01日, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0027997054&origin=inward
    概要:Moisture sorption properties of gelatin powder and collagen fibers were investigated on the basis of the moisture sorption isotherm, the differential heat of moisture sorption, the decrease in entropy of moisture sorption and the parameter constants of the applicable isotherm equation. The amount of moisture sorbed on collagen fibers was larger than that on gelatin powder. The water molecules were absorbed on gelatin itself rather than on the active sites of gelatin. They were adsorbed on the polar groups of constitutive amino acids at amounts of moisture sorbed up to one or two monolayers and then were absorbed into collagen fibers at higher monolayers. They were kept loosely in gelatin and tightly in collagen. The structural stability of collagen to moisture was higher than that of gelatin.

    概要:Paraquat removal by chitosan with different substituents was investigated in vitro for evaluation of chitosan as a paraquat adsorbent in emergency treatment for acute paraquat poisoning. Chitosan CM and SU, in which the hydroxyl group at the C6 position is replaced by a carboxymethyl and sulfonic group, respectively, removed paraquat abundantly in purified water. However an inhibitory effect of sodium chloride on paraquat removal by CM and SU was recognized. On the other hand, paraquat removal by cross-linked chitosan (BCW) was accelerated in saline solutions. It was recognized that more paraquat was removed by BCW chitosan when the sodium chloride concentration was less than 1.8%. It was confirmed that some chitosan beads (CM and SU) could function as effective paraquat adsorbents through in vitro experiments.
  • Moisture Sorption Properties of Collagens Varied in Polarity and Porous Structure by Alkali-Treatment, Keito Boki, Naohito Kawasaki, Hitoshi Takahashi, Journal of Colloid And Interface Science, 161, 1, 148, 154,   1993年11月01日, 10.1006/jcis.1993.1453, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=0001087739&origin=inward
    概要:Moisture sorption properties of steer hide collagen fibers treated with calcium hydroxide were investigated on the basis of sorption isotherm, differential heat of sorption, entropy of moisture sorption, and applicability of isotherm equations to elucidate the difference between untreated and treated collagens in interaction with water molecules. The alkali-treatment resulted in the occurrence of new and more active sorption sites, the increases in both number of free carboxyl and void space of collagen molecules, and also the change to a more disentangled structure. The increase in moisture content and the changes in interactive force between water molecules and various sorption sites of collagens at different ranges of water activity (Aw) were attributed to the changes in number and strength of polar groups and in inner space of collagens due to alkali-treatment. Sorption characteristics of moisture on collagen could well be explained by the strength of interaction of water with collagen and the surface hydrophobicity of collagen. The Henderson and Chung and Pfost equations fitted the moisture sorption isotherms well over a wide Aw range up to 0.90. The large values of constants in the equations to the moisture sorption isotherms of collagens indicated both unstability of the collagen structure to moisture and negative electrification due to polar groups on the surface of collagen. © 1993 Academic Press.

    概要:Nitrogen adsorption and desorption isotherms on untreated collagen fiber and collagen fibers treated for 10, 20, and 30 days with calcium hydroxide were investigated. Surface area of the untreated collagen fiber was 2.2 m2/g. Pore size distributions of the collagen fibers were calculated by the micropore method and the Dollimore-Heal method from the adsorption isotherms to elucidate the relationship between alkali treatment period and porosity. The differential micropore volumes, with radii of 15.5 to 24.5 Å, and the cumulative pore volumes, with radii larger than 12 Å, of the collagen fibers treated for 20 days were the largest. The result was well explained by the results of the C constant calculated from the BET equation. © 1993 Academic Press. All rights reserved.

  • Adsorption isotherms of pigments from alkali-refined vegetable oils with clay minerals, Keito Boki, Moriaki Kubo, Naohito Kawasaki, Hidehito Mori, Journal of the American Oil Chemists' Society, 69, 4, 372, 378,   1992年04月01日, 10.1007/BF02636071, http://www.scopus.com/inward/record.url?partnerID=HzOxMe3b&scp=51249167886&origin=inward
    概要:Adsorption isotherms of pigments from alkali-refined oils (rapeseed, soybean, wheatgerm, safflower, corn, cottonseed and sunflower) were measured to investigate the applicability of the Langmuir and Freundlich equations and to elucidate the adsorption characteristics of pigments on sepiolites and standard activated clay. The Freundlich equation was more applicable to the experimental adsorption isotherms. The equilibrium amount adsorbed, acidity, pore size distribution and inflection of the Freundlich isotherms could be explained by assuming that pigments were adsorbed on the stronger acid sites in smaller pores at low concentration, and then in the larger ones when the concentration increased. The amount adsorbed increased with a rise in adsorption temperatures from 70 to 110°C, and the heat of adsorption was below 10 kcal/mol. The results indicate that pigments were physically adsorbed on the acid sites activated at higher adsorption temperatures. © 1992 American Oil Chemists' Society.
