聚丙烯腈螯合纤维的研究进展

Progress in polyacrylonitrile chelated fiber

聚丙烯腈纤维(PAN)上的AN侧基可与多种物质反应,生成能够与金属离子配位的PAN螯合纤维,这已成为近年来一个重要的研究热点。归纳了PAN螯合纤维与金属离子的配位吸附原理及其制备方法;综述了国内外研究进展;对其在工业废水治理(包括吸附重金属离子、降解有机物催化作用)、痕量稀贵金属的富集与回收,以及对抗菌材料等方面应用研究的国内外现状作了简介。

After the nitrile groups reacting with a variety of substances,PAN fiber will become polyacrylonitrile chelated fiber that can be coordinated with heavy metal ions.It has become an important hotspot in recent years.The chelated mechanism and the methods of preparation were induced and the research status on PAN chelated fiber were summarized.The application research at home and abroad,industrial wastewater treatment（adsorption of heavy metal ions,catalytic degradation of organic matter）,enrichment and recovery of trace metals and the antibacterial materials were introduced.
