利用预辐照接枝法合成了聚丙烯胺肟（ＰＰＡＯ）螯合纤维，研究了影响接枝率、胺肟基因含量及离子吸附的因素。该纤维对铜（Ⅱ）离子的吸附容量达０．６７ｍｍｏｌ／ｇ干纤维。
Polypropylene amidoxime (PPAO) chelate fiber was synthesized by the pre - irradiation grafting method. The factors affecting the grafting rate, the content of amidoxime gene and the ion adsorption were studied. The copper (Ⅱ) ion adsorption capacity of the fiber up to 0.67mmol / g dry fiber.
