The cation-exchange characteristics of 15 elements with the strongly acidic cation-exchange resin Dowex 50 x 8 were investigated in media containing varying concentrations of organic solvents and aqueous hydrofluoric acid. The determination of the distribution coefficients was carried out in 0.15-1.2 M hydrofluoric acid solutions containing 0-90% of the organic solvents methanol, ethanol, n-propanol, isopropanol, methyl glycol, acetone, tetrahydrofuran, and acetic acid. Based on these distribution data the possibilities of separations of the various elements are indicated and discussed.
研究了15种元素在含有不同浓度有机溶剂和氢氟酸水溶液的介质中与强酸性阳离子交换树脂Dowex 50 x 8的阳离子交换特性。在含有0-90%有机溶剂甲醇、乙醇、正丙醇、异丙醇、甲基乙二醇、丙酮、四氢呋喃和乙酸的0.15-1.2M氢氟酸溶液中进行分配系数的测定。基于这些分配数据，指出并讨论了各种元素分离的可能性。
