Study on the simultaneous adsorption of CTMAB-HTCC bentonite towards aniline and Cd~(2+)
Source abstract
Abstract
CTMAB-HTCC bentonite was prepared using bentonite modified with cetyltrimethyl ammonium bromide and quaternized chitosan.This organo-bentonite was applied in the simultaneous adsorption of CTMAB-HTCC bentonite towards aniline and Cd2+ from aqueous solution.During the experiments,the effects of pH,absorbent dosage,adsorption time,the initial concentration,etc on adsorption were all discussed.The results show that CTMAB-HACC bentonite effectively removes aniline and Cd2+ from aqueous solution simultaneously.The main adsorption mechanisms for aniline and Cd2+ are partitioning effect and chelation action,respectively.The presence of Cd2+ has no influence on the adsorption of aniline,while the presence of aniline can improve the adsorption of Cd2+ onto CTMAB-HACC bentonite.
