五十年代出现的离子交换纤维是在纤维的高分子链上带有离子交换基团的离子交换材料。由于其比表面较常用的离子交换树脂大,且交换基团配置在纤维表面,故吸附、解脱速度快,交换效率高,在富集和分离元素方面得到了实际应用。其中黄原酯棉(CottonCellulose Xanthate,简称CCX)与巯基棉比较,又具有制备简单,无巯基乙醇酸恶嗅味, Fifties appeared in the ion exchange fiber is the fiber in the polymer chain with ion exchange groups ion exchange material. Because of its larger surface area than the commonly used ion exchange resin, and the exchange group disposed on the fiber surface, so adsorption, release speed, exchange efficiency, in the enrichment and separation of elements has been the practical application. Among them, Cotton Cellulose Xanthate (CCX) has the advantages of simple preparation, no bad smell of thiol glycolate,
