Abstract: Metal ion-imprinted polymers are prepared by surface template polymerization, an emulsion polymerization process which utilizes a functional monomer, an emulsion stabilizer, a polymer matrix-forming co-monomer, and a print molecule. Such surface-templated polymers offer high sorption rates for metal ions as well as high selectivity. For this technique, the interfacial activity of the functional monomer is a vital factor for the selection of a suitable metal ion-binding amphiphile. It is also an important factor for the firm attachment of the functional monomer onto the polymer matrix. We have succeeded in preparing highly selective ion-imprinted polymers by two approaches: a) the design of functional monomers; and b) post-irradiation with gamma rays to make the polymer matrix more rigid. Adsorption behavior of Zn(II) and Cu(II) by the newly synthesized polymers has been evaluated. The imprinting effect on metal-ion adsorption efficiency and selectivity is discussed
