Abstract: A novel type ion imprinted polymer(IIP) was prepared by molecular imprinting technology(MIT).The selectivity and adsorption capacity for the Cd(II) ions of Cd(II)-MIP were systematically studied in this paper.The IIP was prepared by bulk polymerization using Cd(II) ion as a template,a-benzoin oxime as a functional monomer and ethylene glycol dimethacrylate(EGDMA) as a crosslinker.The results obtained show that,in comparison with non-imprinted polymer,the sorption equilibrium was achieved in 50 min and the maximum sorption of Cd(II) imprinted polymer was about 2.12 mg/g.The mechanism for the adsorption of Cd(II) on the imprinted polymers were investigated.
