Abstract: A new Pb (II) ion-imprinted polymer (Pb (II)-IIP), which can be used for selective adsorption of Pb (II) from aqueous solutions, was successfully prepared based on silica gel particles with the help of surface molecular imprinting technology. The adsorption kinetic curve, adsorption isotherm and selective adsorption were measured by static method. The adsorption kinetics of IIPs for Pb (II) reached the equilibrium at about 20 min. The maximum adsorption capacity was 22.72 mg/g, and the IIPs had much higher adsorption quantity than NIPs. Competitive adsorption studies showed that Pb (II)-IIP offers the advantages of selectivity toward targeted Pb (II) compared with NIP in the presence other metal ions. The results showed that the IIPs possessed good specific adsorption capacity and selectivity for Pb (II).
