摘　　要：阐述了湿法腈纶用溶剂硫氰酸钠的净化方法，并对国内的几种溶剂净化方法作了比较，提出了在湿法腈纶生产企业中，应利用分步结晶法与其他净化方法相结合，但也不能忽视阻滞除杂法的发展。The cleaning method of NaSCN solution for PAN fiber industry was discussed. By comparing with several solution methods in China, it was suggested that we should select process crystallization combining with other methods; meanwhile, it was necessary to emphasize the development of the hindered exchange method.
