Moは比放射能が低いことから、医療用Mo吸着材として高いMo吸着性能を有する材料が求められている。このため、メソポーラス構造を持つアルミナの開発を進めている。本研究では、メソポーラスアルミナ(MA)を開発し、比表面積や結晶構造の違いによるMo吸着性能の評価を行った。この結果、焼結温度の違いによるMAの気孔径や比表面積の違いを明らかにするとともに、Mo溶液の違いによるMo吸着性能を明らかにした。

被引用回数：204 パーセンタイル：99.59(Engineering, Chemical)In this study, the effectiveness of amberlite IRA-938 resin for Rose Bengal (RB) dye removal from aqueous phase was evaluated. For the RB dye removal, equilibrium was achieved within 45 min because rate of adsorption was fast. The adsorption equilibrium for RB dye onto amberlite IRA-938 resin was in good agreement with Langmuir adsorption isotherm. It was observed that amberlite IRA-938 resin had excellent RB dye adsorption capacity. The environmental applicability of amberlite IRA-938 resin was performed in the separation of RB dye from the tap water sample spiked with 50 mg/L RB dye solution. The breakthrough and exhaustive capacity were 100 and 325 mg/g, respectively.

The effects of several physicochemical parameters such as contact time, initial bromate concentration, initial pH, and temperature were studied. The concentration of bromate was determined using ultra-performance liquid chromatography tandem mass spectrometry. The adsorption kinetics and isotherms were well fitted by pseudo-second-order model and Freundlich model, respectively.

被引用回数：249 パーセンタイル：99.32(Engineering, Environmental)A novel Schiff base ligand based nano-composite adsorbent (NCA) was prepared for the detection and removal of copper (Cu(II)) ions in wastewater samples. Upon the addition of Cu(II) ions to NCA at optimum conditions, the clear color was visible to the naked-eye in the detection system. This NCA exhibited an obvious color change from yellowish to dark green in the presence of Cu(II) ions in aqueous solution. The NCA could detect the Cu(II) ions over other foreign ions with high sensitivity and selectivity. For adsorption behaviour, influences several factors such as solution pH, contact time, concentration for Cu(II) ion adsorption was investigated by batch experiment in detail. The results showed that neutral solution pH was suitable to get optimum Cu(II) ions adsorption.

被引用回数：60 パーセンタイル：84.07(Chemistry, Multidisciplinary)A new surfactant-based nanocomposite cation exchanger, sodium dodecyl sulfate-Th(IV) tungstate (SDS-TT) was prepared by the sol-gel method. The SDS-TT was characterized by FTIR, XRD, TGA, SEM, EDS and TEM. The distribution studies for various metal ions on SDS-TT were performed in different acidic mediums. On the basis of distribution coefficient values, SDS-TT was found to be selective for Cu metal ion. SDS-TT was successfully used for the quantitative separation of Cu from the synthetic mixture, pharmaceutical formulation and brass sample.

被引用回数：273 パーセンタイル：99.62(Chemistry, Physical)In the current study, Ti(IV) iodovanadate cation exchanger (TIV) was synthesized and applied for the removal of Pb and Hg metal ions from the aqueous medium. The adsorption studies were performed by the batch techniques and adsorption parameters viz. contact time, pH, initial metal ion concentration, and temperature were also investigated. The optimum adsorption of Pb and Hg were observed at pH6. The pseudo-second order equation represented the adsorption kinetics with high correlation coefficient. Langmuir model showed the best fitting to the isotherm equilibrium data, with a maximum adsorption capacity of 18.8 mg/g for Pb and 17.2 mg/g for Hg.
