概要:

Heavy metals in the water environment, such as arsenic, chromium, lead, zinc, copper, and cadmium, caused great harm to human beings and aquatic organisms. Therefore, removal of the metal ions from wastewater has attracted extensive research interests. In addition, recovery of valuable metals together with removal of toxic metals is considered. Among conventional techniques, adsorption technique becomes one of the alternative treatments, due to high efficiency, low … cost, and easy operation. In this study, adsorptive separation of heavy metals from aquatic environment was investigated with three main topics. Firstly, adsorptive removal of arsenic was investigated employing two resins CRB05 with N-methyl-D-glucamine group and Lewatit FO36 with FeOOH group. Secondly, reductive adsorption of Cr(VI) was investigated using coal-based activated carbon. Thirdly, selective adsorption of Pb(II) from aqueous solution containing Pb(II), Cu(II), Zn(II), and Cd(II), was investigated, using chelating resin CR11 with iminodiacetic-acid group, goethite, and magnetite. 続きを見る
