摘　　要：利用（６０）ＣＯγ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－ＡＡ）螯合纤维。预辐照剂量和接枝单体的比率对接枝率、胺肟基因含量和吸附容量有影响。研究了ＰＶＡＡＯ－ＡＡ螯合纤维对钯的吸附性能。Polyviny1 alcoho1 amidoxime chelate fiber containing groups (PVAAO-AA) was synthesized by preirradiation graft copolymerization and amidoximation. The irradiation dose and ratio of monomer (acrylonitrile and acrylic acid), influence the percentage of grafting, content of amidoxime group in the grafted product and its adsorption capacity. The behaviour of palladium (Ⅱ) ion adsorption was systematically studied in this paper.
