本文介绍了偕胺肟螯合纤维的制备方法及对银的吸附性能。脱水聚乙烯醇纤维与丙烯睛反应制得氰乙基化纤维。再与盐酸羟胺反应把氰乙基化纤维转化为偕胺肟纤维。该螯合纤维对银的吸附容量达0.3mmol/g。吸附速度也很快。
This article describes the preparation of amidoxime chelate fiber and silver adsorption properties. Dehydration of polyvinyl alcohol fiber and acrylonitrile reaction of cyanoethylated fibers. Reacts with hydroxylamine hydrochloride to convert cyanoethylated fibers to amidoxime fibers. The chelating fiber has a silver adsorption capacity of 0.3 mmol / g. Adsorption speed is also fast.
