    Summary:Aluminum oxyhydroxide (boehmite, BE) shows adsorption ability of arsenious ion. In this study, we calcined BE in the temperature range 200-1150 degrees C, and examined the amount of arsenious ion adsorbed and adsorption mechanism. As a result, the adsorption amount of arsenious ion by BE calcined at 400 degrees C showed the highest value as compared with those by BE calcined at other temperatures. On the other hand, the amounts of arsenious ion adsorbed onto BE showed lower values at 200, 600, and > 1000 degrees C than that by BE before calcination. The amount of surface hydroxyl group of calcined BE showed the highest value at the calcination temperature of 400 degrees C. As a result of X-ray analysis, BE showed boehmite structure at less than the calcination temperature of 300 degrees C, while BE was converted to the transitional state of aluminum oxide at more than 400 degrees C. From the result of the amount of arsenious ion adsorbed and FT-IR, it turned out that calcined BE dissociated water molecule when suspended in the water, hydroxyl group was generated on the surface, and the amount of arsenious ion adsorbed was increased because of the ion exchange of these hydroxyl groups with arsenious ions. It was clarified that an adsorbent with high adsorption ability of arsenious ion was obtained by calcination of BE. (c) 2006 Elsevier Inc. All rights reserved.
  • Structure transformation of gibbsite by calcination, Fumihiko Ogata, Naohito Kawasaki, Mineaki Kabayama, Takeo Nakamura, Seiki Tanada, e-Journal of Surface Science and Nanotechnology, e-Journal of Surface Science and Nanotechnology, 4, 267 - 269, Mar. 11 2006
    Summary: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.
  • Survey on cellular phone usage on students in Thailand, Naohito Kawasaki, Shigeharu Tanei, Fumihiko Ogata, Siriporn Burapadaja, Chaowalit Loetkham, Takeo Nakamura, Seiki Tanada, Journal of Physiological Anthropology, Journal of Physiological Anthropology, 25(6), 377 - 382, 2006
    Summary:The number of cellular phone subscribers is increasing every year and there have been reports of health disorders related to the high-frequency radio waves. This paper considers the dependence of Thai university and high school students on cellular phones. A survey form (cellular phone dependence questionnaire: CPDQ) was distributed to 181 female and 177 male Thai university students and to 240 female and 140 male Thai high school students. The surveys were collected, Cronbach α coefficient was calculated, and a factor analysis was performed using the principal factor method and varimax rotation. The total scores were 16.54 to 20.04 and the Cronbach's α coefficients were 0.808 to 0.930. According to a factor analysis of 20 scored items, 4 factors were extracted for both male and female high school students, and the cumulative correlation coefficients of the male and female groups were 64.85% and 62.70%, respectively. Five factors were extracted for male university students and 6 factors were extracted for female university students, and the cumulative correlation coefficients were 58.08% and 57.91%, respectively. The W value results of the Shapiro-Wilk W-test for male university students, female university students, male high school students and female high school students were 0.969, 0.984, 0.964, and 0.913 respectively, thus verifying the normality of the score distributions. The total scores for the Thai university students were higher than the scores for the Thai high school students. The factor analysis of female high school students confirmed a large difference compared to male university students, male high school students, and Japanese female university students. (The Japanese students were surveyed in an earlier study by Toda et al.). Also, the CPDQ total score was high, which indicated a strong tendency toward dependence.
  • Removal of Lead and Iron Ions by Vegetable Biomass in Drinking Water, Ryoma Bun-Ei, Naohito Kawasaki, Fumihiko Ogata, Takeo Nakamura, Katsuyori Aochi, Seiki Tanada, Journal of Oleo Science, Journal of Oleo Science, 55(8), 423 - 427, 2006
    Summary:Vegetable biomass available in all regions of the world was focused on for the purposes of effectively utilizing food wastes, attempting to reduce the emission of carbon dioxide, and developing simple water treatment techniques in developing country. In this study, the adsorption characteristics of heavy metal ions onto vegetable biomass as bean curd lees (BC), corn cobs (CO), and wheat bran (WB) were investigated. In single solution system, larger amounts of iron ion were adsorbed onto BC than onto CO and WB. Iron and lead ions were also found to compete in adsorption to BC in binary solution system. Furthermore, the amounts of the heavy metal ions adsorbed depended on the protein content of the vegetable biomass. However, because the vegetable biomass is rich in nutrients, they are likely to render drinking water treated with them liable to putrefaction. Although viable bacterial counts increased in water with the vegetable biomasses added, the water is considered suitable for drinking for 48 h or less after the treatment. © 2006, Japan Oil Chemists' Society.

  • Relationship between Surface Polarity and Moisture Control onto Carbonaceous Materials Produced from Bean Curd Lees, Ryoma Bun-Ei, Naohito Kawasaki, Takeo Nakamura, Fumihiko Ogata, Seiki Tanada, Journal of Oleo Science, Journal of Oleo Science, 55(1), 23 - 29, 2006
    Summary:In order to promote the shift to zero emissions of organic wastes, it is necessary to create carbon cycling processes. On the other hand, one of the distinguishing features of the Japanese climate is its high humidity, and an adsorbent which is high ability of moisture control are needed to prevent putrefaction of wood and keep indoor spaces at a comfortable humidity. This research focused on producing a carbonaceous material produced from bean curd lees, which is a form of food waste, and studied the relationship between the surface polarity or specific surface area of carbonaceous material, and the ability of moisture control. The specific surface area of the carbonaceous material was measured, and the highest value was exhibited in carbonaceous material produced at a temperature of 1173K. From this result, it appears that a microstructure develops as the carbonization temperature increases, but when the carbonization temperature is increased further, the specific surface area decreases due to merging of pores. Also, the ability of moisture control of charcoal is 22, and the ability of moisture control of the carbonaceous material produced from bean curd lees is a maximum of 198. This suggests that the material can be used in applications as a moisture control material. This work clarified that the ability of moisture control of the carbonaceous material increases to the degree that there are fewer phenolic hydroxyl groups and carboxyl groups in the carbonaceous material surface. © 2006, Japan Oil Chemists' Society.

  • Deodorization of Ammonia by Coffee Grounds, Naohito Kawasaki, Hideo Kinoshita, Takashi Oue, Takeo Nakamura, Seiki Tanada, Journal of Oleo Science, Journal of Oleo Science, 55(1), 31 - 35, 2006
    Summary:Coffee grounds are a vegetable biomass that can be efficiently burned. The carbon dioxide generated by burning coffee grounds is affecting global warming. On the other hand, ammonia generated in the places such as toilets or farms produces a bad smell. In the present study, we have analyzed the possibility of ammonia elimination using the carbonaceous materials produced from coffee grounds. Carbonaceous materials were prepared by the microwave treatment of coffee grounds. We observed that the saturated amounts of ammonia adsorbed by some of the carbonaceous materials produced from coffee grounds were greater than that adsorbed by activated carbon. In contrast, the activated carbon adsorption rate for ammonia was higher than those of the carbonaceous materials. Therefore, carbonaceous materials produced from coffee grounds could be utilized for the removal of ammonia in the gaseous phase. © 2006, Japan Oil Chemists' Society. All rights reserved.
  • 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, e-Journal of Surface Science and Nanotechnology, 3, 63 - 69, Feb. 20 2005
    Summary: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, T Tokimoto, N Kawasaki, T Nakamura, J Akutagawa, S Tanada, JOURNAL OF COLLOID AND INTERFACE SCIENCE, JOURNAL OF COLLOID AND INTERFACE SCIENCE, 281(1), 56 - 61, Jan. 2005
    Summary: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. (C) 2004 Elsevier Inc.

  • Study on adsorption kinetic of aromatic hydrocarbons onto activated carbon in gaseous flow method, N Kawasaki, H Kinoshita, T Oue, T Nakamura, S Tanada, JOURNAL OF COLLOID AND INTERFACE SCIENCE, JOURNAL OF COLLOID AND INTERFACE SCIENCE, 275(1), 40 - 43, Jul. 2004
    Summary:The adsorption behavior of benzene, toluene, o-xylene, m-xylene, and p-xylene onto activated carbon was investigated using the flow method. The removal efficiency of aromatic hydrocarbons in the gaseous phase was estimated based on the adsorption kinetic constants and the saturated amount of aromatic hydrocarbons adsorbed on the activated carbon. The saturated amount of benzene and toluene adsorbed was greater than that of xylene adsorbed because the molecular sizes of benzene and toluene are smaller than that of xylene. The adsorption kinetic constant increased in the order of xylene, toluene, and benzene. Those of the three xylene isomers were similar. These results indicated that the adsorption rate of benzene by the activated carbon was the fastest and the kinetic constant depended upon the different between the boiling point and the melting point and the molecular size of the aromatic hydrocarbons.

  • Adsorption of fluoride ions onto carbonaceous materials, Abe, I, S Iwasaki, T Tokimoto, N Kawasaki, T Nakamura, S Tanada, JOURNAL OF COLLOID AND INTERFACE SCIENCE, JOURNAL OF COLLOID AND INTERFACE SCIENCE, 275(1), 35 - 39, Jul. 2004
    Summary: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. (C) 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 01 , 10.1080/02772240400007096
    Summary: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.

    Summary: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.

    Summary: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.

    Summary: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.

    Summary: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.
