Pb2+-imprinted polymer particles were prepared by surface molecular imprinting technique and sol-gel process with Pb2+ ion as the template,chitosan as the functional monomer,silica gel as the carrier,and KH-560 as the cross-linking agent. Both the imprinted and non-imprinted polymer particles were characterized by FT-IR,UV-spectra,and scanning electron microscopy. The effect of adsorption acidity,sorbent dosage and resting time on adsorption rate was investigated by inductively coupled plasma atomic emission spectrometry. Selectivity for Pb2+ ions of the prepared polymer was also studied in mixed aqueous solution. Adsorption capacity of Pb2+-imprinted polymer was compared with that of non-imprinted polymer. Finally,imprint and adsorption mechanism was also put forward. The optimum acidity for quantitative enrichment was around pH 4.5 and the adsorption equilibrium could be reached in five hours. Pb2+-imprinted polymer exhibited high selectivity for Pb2+ ions,and its adsorption capacity was two times higher than that of non-imprinted polymer.
