Abstract: Pb(II) and Cu(II) ion imprinted polymer particles were prepared by the combination of surface molecular imprinting technique and sol-gel process in acetic acid solution, with Pb(II) or Cu(II) ion as a template, CTS as functional monomer, and KH-560 as the cross-linker. The configuration of ion imprinted polymer and its materials were characterized by FT-IR spectra, UV-spectra. The optimal adsorption conditions, such as acidity, resting time, amount of sorbent etc, were investigated by flame atomic adsorption spectroscopy (FAAS). Selectivity of the prepared ion imprinted polymers in dilute aqueous solution was examined by ICP-AES. It was found that adsorption capacity of Pb(II) and Cu(II) ion imprinted polymer was found to be 24.3 and 50.3 mg/g, respectively. And ion imprinted polymers exhibited higher selectivity for template ions than non-imprinted polymer in the mixed aqueous solution
