摘　　要：利用６０Ｃｏγ射线预辐照接枝和胺肟化反应合成了聚乙烯醇胺肟（ＰＶＡＡＯ）螯合纤维，研究了它对４种金属离子的螯合性能。结果表明，预辐照剂量对接枝率、胺肟基团含量和吸附容量均有影响。在ｐＨ＝５时，该纤维对Ｃｕ（Ⅱ）离子的吸附容量达１．０５、ｍｍｏｌ／ｇ干纤维。Polyvinyl acohol amidoxime chelate fiber (PVAAO) was synthesized bypreirradiation graft copolymerization and amidoximation. The chelating properties for Cu(Ⅱ), Pd(Ⅱ), Au(Ⅲ) and Hg(Ⅱ) ions have been studied.The experimental results showed that the irradiation dose influences the percentage of grafting, content of amidoxime group in the grafted product and its adsorption capacity. The adsorption capacity for metal ion Cu(Ⅱ) is 1.05mmol/g dry fiber.
