Abstract: The metal ion selective resins were prepared by surface template polymerization by using monooleyl phosphoric acid (1), oleyl Me phosphoric acid (2), or oleyl Et phosphoric acid (3) as amphiphilic host surfactant. The Cu2+-imprinted resins prepared in the presence of Cu2+ adsorbed Cu2+ much more effectively than did their reference resins. The Cu2+-imprinted resins showed much less binding ability toward Zn2+. The template-dependent selectivity should be ascribed to a favorable placement of the surface-anchored metallophilic groups for multidentate coordination to specific metal ion.
Template and target information: copper ion, Cu(II)
