摘要
研究流脲棉纤维的合成方法及其对银离子的吸附性能．该合成纤维对银离子的吸附率高达９５％，且吸附反应速度快；被吸附的银离子用４ｍｏｌ·Ｌ－１硝酸洗脱，洗脱率为９５％．实验表明，该合成纤维不仅合成方法简单，而且分离操作方便，可应用于银的富集和分离．
Thiourea cotton fiber as a new type fiber is prepared by the reaction of thiorea with acetylated cotton fiber under given conditions. The method of its synthesis and its adsorption of silver ion are described.This synthetic fiber shows a silver ion adsorption ratio as high as 95% and a fast adsorption. The adsorbedsilver iou can be eluted by 4 mol· L-1 HNO3,with an elution rate approaching 95%. The synthetic fiber isshown experimeatally to have a long length of life. It can be used repeatly, with a good reproducibility. It issimple in synthesis, easy and convenient in operation. It can be applied to the enrichment and seperation ofsilver.
