Abstract

Cu<sup>II</sup>-imprinted microspheres with imidazole groups at the surfaces were prepared from a seed emulsion with divinylbenzene as a matrix-forming monomer and Cu<sup>II</sup> as a template by radical polymerization. The seed emulsion was prepared from the polymerization of 1-vinylimidazole, styrene, and <i>n</i>-butyl acrylate mixture by a radical initiator. The obtained microspheres were uniform-sized spherical particles and their average diameter was 0.44 μm based on scanning electron micrography. The adsorption of the Cu<sup>II</sup> ion (0.05 mM) on these microspheres was studied, and compared to non-imprinted ones. The adsorption of Cu<sup>II</sup> ion increased on both microspheres with increasing pH. The template effect was observed, that is, the pH giving 50% adsorption of Cu<sup>II</sup> ion on Cu<sup>II</sup>-imprinted resin was lower by one unit than that on non-imprinted resin. The template effect was also observed for the Zn<sup>II</sup> ion, but not observed for the Cd<sup>II</sup> ion.<br>
