摘　　要：利用６０Ｃｏ－γ射线预辐照接枝和胺肟化反应合成了含羧基的聚乙烯醇胺肟（ＰＶＡＡＯ－ＡＡｃ）螯合纤维。预辐照剂量和接枝单体的比率对接枝率和胺肟基团含量有影响。研究了ＰＶＡＡＯ－ＡＡｃ螯合纤维对金的吸附性能。Polyvinyl alcohol amidoxime chelate fiber containing carboxyl groups(PVAAO AAc) was synthesised by preirradiation graft copolymerization and amidoximation. The irradiation dose and ratio of monomer(acrylonitrile and acrylic acid) influence the grafting and content of amidoxime group in the grafted product. The behaviour of gold(Ⅲ) ion adsorption was systematically studied in this paper.
