Abstract
摘要 本文描述了利用离子交换树脂提纯硫酸锌的方法。用亚硝基红盐作络合剂,它与硫酸锌中的重金属离子生成络合阴离子,通过阴离子树脂的交换作用而被除去。文中讨论了某些树脂的性能、络合剂的用量、交换条件和树脂再生方法,并给出对产品质量进行检验的结果。离子交换树脂也可以用来提纯锌、镁、钙、锶、钡、钠等的氯化物和某些硫酸盐。 Abstract A method of purifying ZnSO4 by ion exchange resin is described. The nitroso-R=salt is selected as the anionic complex-formation agent, with the help of which heavy metal ions in ZnSO4 solution are seperated out by the anion exchanger. The properties of some resins from different manufacturers, the amonnt of anionic complex-formation agent to be applied, the condition under which ion exchange takes place and the regeneration of resin are presented. Results of testing of the final product by different methods are given.lon exchanger may also be utilized for the purification of chlorides of Zn, Mg, Ca, Sr, Ba, -Na, etc., and some of the sulfates. 作者及机构信息 王芳人 Authors and contacts WANG FANG-JEN 参考文献 [1] 施引文献
