Abstract

In the present paper the cation-exchange characteristics of 20 elements towards the strongly acidic cation-exchange resin Dowex 50 X 8 in media containing varying concentrations of organic solvents and aqueous hydrochloric acid were investigated. Based on the determination of the distribution coefficients of these elements in the organic solvents methanol, ethanol, n-propanol, isopropanol, methyl glycol, acetone, tetrahydrofuran, and acetic acid, the conditions most suitable for their quantitative separation are indicated and discussed.

摘要

本文研究了在含有不同浓度有机溶剂和盐酸的介质中，20 种元素对强酸性阳离子交换树脂 Dowex 50 X 8 的离子交换特性。通过测定这些元素在有机溶剂甲醇、乙醇、正丙醇、异丙醇、甲基乙二醇、丙酮、四氢呋喃和乙酸中的分配系数，指出并讨论了最适合它们定量分离的条件。
