摘要

In this study, a novel ion-imprinted polymer (IIP) was synthesized using attapulgite (ATP) and chitosan (CS) as the substrates and methyl methacrylate (MMA) as the monomer. The IIP (MMA) was characterized by FTIR, XRD, SEM, TEM, BET, and XPS. Orthogonal experiments were analyzed to show that when initial concentration of Cd2+ was 100 mg/L, and the adsorption time was 20 min, under the condition of IIP (MMA) and NIP (MMA) on Cd adsorption capacity, were 57.56 mg/g and 52.03 mg/g, at the same time, the adsorption capacity of Se were 17.14 mg/g and 15.86 mg/g, far below the Cd adsorption capacity. The results showed that IIP(MMA) synthesized with ATP and CS as substrates and MMA as functional monomer has been successfully synthesized and can be used for selective adsorption of Cd2+ in water.
