本文研究了550螯合树脂对铜的吸附性能,进行了分离富集条件的选择,观察了铜与钴等多种共存离子的分离效果。结果表明,550螯合树脂对铜吸附性能良好,能从大量钴中分离微克量铜。拟定了钴电解液中微量铜的测定方法。初步应用效果好。回收率为90—102％,相对标准偏差小于5％。
In this paper, the adsorption properties of copper on 550 chelating resins were studied. The conditions of separation and enrichment were selected. The separation effects of various coexisting ions such as copper and cobalt were observed. The results show that the 550 chelating resin has good adsorption capacity for copper and can separate micrograms of copper from a large amount of cobalt. A method for the determination of trace amounts of copper in cobalt electrolyte was developed. Preliminary application effect is good. The recovery rate was 90-102% and the relative standard deviation was less than 5%.
