The graft polymerization of acrylonitrile on Crosslinked polyvinyl alcohol microspheres CPVA microspheres was performed by using cerium ammonium sulfate as initiator, and grafted microspheres CPVA-g-PAN were prepared. Subsequently, the grafted PAN was converted into poly via amidoximation reaction with hydroxylamine hydrochloride as reagent, resulting in the functional microspheres CPVA-g-PAO. The chemical structure and physicochemistry characters were adequately characterized with infrared spectrum, scanning electron microscope and determining Zeta potential. The effects of main factors on the amidoximation transform reaction of the grafted PAN were researched with emphasis, and the adsorption property of the functional microspheres CPVA-g-PAO for some biomolecules was examined preliminarily with uric acid as a model biomolecule.
