Abstract

The paper analyzes polymer fibrous ion-exchange materials on the basis of polyacrylonitrile matrix released as KN1 cation exchanger and AS-1 and AN-1 anion exchangers. The purpose is to study the sorption properties of the specified materials in relation to multicomponent salt solutions of heavy metals. According to obtained results, the exchange processes are characterized by high speed, and materials – by high exchange capacity. The cascade filtration purifies heavily polluted industrial waste waters to the levels of 10 mg/l of Pb (II), Zn(II), CD (II), Cu(II), Mo(VI), W(VI) thus fully satisfying hygienic requirements. The advantages of the studied materials include low flow resistance, a possibility of repeated regeneration (with acid and alkali) with desorption of valuable components and creation of waste-free or low-waste technologies on their basis.

纤维离子交换材料处理强污染工业废水的卫生效果

本文在聚丙烯腈基体作为KN1阳离子交换剂和as -1、AN-1阴离子交换剂释放的基础上，对聚合物纤维离子交换材料进行了分析。目的是研究特定材料对重金属多组分盐溶液的吸附性能。所得结果表明，该交换过程具有速度快、交换容量大的特点。级联过滤将重污染工业废水的Pb (II)、Zn(II)、CD (II)、Cu(II)、Mo(VI)、W(VI)净化到10 mg/l的水平，完全满足卫生要求。所研究材料的优点包括低流动阻力，通过解吸有价值的成分(酸和碱)重复再生的可能性以及在其基础上创造无废物或低废物技术。
