摘要

利用,60,Co γ预辐照接枝和胺肟化反应合成了聚丙烯胺肟（PPAO）螯合纤维。研究了影响接枝率、胺肟基团含量和吸附容量的因素。结果表明，接枝率随预辐照剂量、反应时间和单体浓度的增加而增加。羟胺溶液的pH=7时，胺肟基团含量最高。吸附容量随胺肟基团含量的增加而增加，该纤维对金的饱和吸附容量为0.51mmol/g干纤维，对钯和铜也有较高的吸附容量。

Abstract

Polypropylene amidoxime chelate fiber was synthesized by preirradiation graft copolymerization and amidoximation. The influence factors of grafting rate,content of amidoxime group and adsorption capacity have been studied. The results of experiment showed that grafting rate increased with the increase of preirradiation dose,grafting reaction time,monomer concentration and grafting reaction temperature. The highest content of amidoxime group is obtained at pH=7 of hydroxylamine solution. The adsorption capacity for gold is 0.51 mmol/g dry fiber.
