The cation-exchange characteristics of 19 elements in hydrobromic acid-organic solvent media have been investigated. In these systems the batch distribution coefficients of the metal ions were determined, using the strongly acidic cation-exchange resin Dowex 50, X8. Methanol, ethanol, n-propanol, isopropanol, methyl glycol, acetone, tetrahydrofuran and acetic acid have been used as the organic solvents. The conditions most suitable for the quantitative separation of the elements are indicated and discussed. Several examples of successful separations are tabulated.
研究了19种元素在氢溴酸 - 有机溶剂介质中的阳离子交换特性。在这些体系中,使用强酸性阳离子交换树脂Dowex 50 X8测定了金属离子的间歇分配系数。甲醇、乙醇、正丙醇、异丙醇、甲基乙二醇、丙酮、四氢呋喃和乙酸被用作有机溶剂。指出并讨论了最适合元素定量分离的条件。列出了几个成功分离的实例。
