Abstract: Metal ion-imprinted polymers may he prepared by surface template polymerization. which is emulsion polymerization utilizing a functional monomer, an emulsion stabilizer, a polymer matrix-forming comonomer, and a print molecule. Such surface-templated polymers offer a high adsorption rate for metal ions as well as high selectivity. For this technique, the interfacial activity of the functional monomer is vital 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: 1) design of functional monomers, and 2) by irradiation with -rays to make the polymer matrix more rigid. Adsorption behavior of several metals by the newly synthesized polymers has been investigated. The imprinting effect on the adsorption ability and selectivity will be discussed
