410哌啶树脂在分离富集中的应用研究  Ⅱ.岩矿中痕量金银铊镓铟的分离富集

摘要: 研究了在HCl(或HBr)介质中410哌啶树脂对Au~(3+)、Ag~+、Tl~(3+)、Ga~(3+)和In~(3+)的吸附特性,考察了被吸附金属离子的分组洗脱或分别顺序洗脱条件,拟定了地质样品中上述诸离子的分离富集程序。经地质标样分析验证,方法可行。

Abstract: Trace amounts of gold,silver,gallium and thallium can be quantitatively separated by adsorption on piperidine resin 410 from 20% HCl. The adsorbed metal ions are eluted with 1. 0% thiourea solution which is useful for the determination of multi-elements.
