Based on the chelating fiber with amidoxime group(AOCF), which is obtained from chemical modification of PAN fiber with hydroxylamine, a series of metal chelating fibers containing amidoxime group are prepared by the reaction of AOCF with metal ion Cu(Ⅱ)?Co(Ⅱ)?Hg(Ⅱ)?Zn(Ⅱ)and Cd(Ⅱ).

A functional material for chelating separation with amidoxime group, is often used in heavy mental ions' (including Uranium, Thorium, rare mental) absorption and enrichment, radiochemical separation and radiochemical waste water disposal.
