摘　　要：介绍了离子阻滞树脂YC-207的特性。讨论了工艺参数对树脂吸附能力的影响。根据离子阻滞法原理,应用YC-207树脂对腈纶溶剂硫氰酸钠溶液进行除杂脱色。该方法具有回收率高,净化效果好,成本低等特点,溶剂内的可溶性杂质(NVI)含量低于5．5％,分析色度(Pt-Co)号低于350,保证了腈纶的质量,纤维一级品率达到99．5％以上。The characteristics of ion-hinder resin YC-207 were introduced. The effects of process parameters on the adsorption capacity of the resin were discussed. The sodium thiocyanate （NaSCN） solution was subjected to impurity removal and decolourization with YC-207 resin according to ion retardant principle, which had the advantages of high recovery ratio, satisfied purification effect and low cost. The soluble non-volatile impurities （NVI） content in the final solvent was lower than 5.5% and the analytical colority （Pt-Co） was below 350. The quality of PAN fiber was guaranteed effectively with the first-rate product above 99.5%.
