摘　　要：利用预辐照接枝法合成了聚乙烯醇双胺肟螯合纤维。研究了影响接枝率和胺肟基团含量的因素，讨论了吸附酸度、吸附时间对Ｃｕ（Ⅱ）离子吸附容量的影响。合成的聚乙烯醇双胺肟螯合纤维对Ｃｕ（Ⅱ）离子的吸附容量达１．６２ｍｍｏｌ／ｇ干纤维，在５ｍｉｎ内达到吸附平衡。The synthesis of polyvinyl alcohol diamidoxime chelate fiber with the method of preirradiation graft copolymerization is reported in this paper The influence factors of grafting and amidoxime group content have been studied The effects of adsorption time, pH value of adsorption solution and amidoxime group content onadsorption capacity for copper(Ⅱ) ions were discussed The adsorption capacity for copper(Ⅱ) ions is 1 62 mmol/g dry fiber
