β-环糊精交联聚合物对铜、铅和锌的吸附性能
Adsorptivity of Acrylamide/β-Cyclodextrin Acylated/Allyl-Biphenyl Ether Crosslinked Copolymer for Cu2+, Pb2+ and Zn2+
摘要
Abstract
β-cyclodextrin crosslinked copolymer AM/β-CD-AA/ABE was synthesized by crosslinking β-cyclodextrin acylated(β-CD-AA) with allyl-biphenyl-ether(ABE):acrylamide(AM) and N,N-methylene double propionamide,and characterized by means of FTIR and TG.The effects of the initial mass concentrations of metal ions(Cu2+,Pb2+ and Zn2+),ion solutionpH and temperature on the adsorptivity of the copolymer were investigated.The results show that the adsorption capacities of AM/β-CD-AA/ABE copolymer for Cu2+,Pb2+ and Zn2+ in solutions are different,among which the static adsorption capacity for Zn2+ is the maximum,50.1 mg/g under the conditions of 35 ℃,initial mass concentration of Zn2+ 200 mg/L and pH 3-4.The adsorption equilibriums of Cu2+,Pb2+ and Zn2+ on the copolymer accord with Freundlich adsorption isotherm.关键词
