Abstract: By using Palygorskite as matrix and introducing the surface ion-imprinting concept to the synthesis process, a Palygorskite-supported organic–inorganic hybrid polymer for selective separation of Pb2+ from aqueous solutio was prepared. The prepared polymer was characterized with techniques of SEM, XRD and FT-IR. The effects of contact time, pH value and temperature of the initial solution on the adsorption characters of Pb2+ were investigated. Under the optimum conditions, the ions-imprinted polymer offered a fast kinetics for the adsorption of Pb2+ and the maximum capacity was 4.51 mg/g. And the pseudo-second order model bestly described the kinetics of adsorption of Pb2+ onto the as-prepared materials.
