Abstract

The anion-exchange characteristics of the platinum metals and gold in hydrochloric acid media are described. The distribution coefficients of these elements were measured on the strongly basic anion-exchange resin Dowex 1 x 8 in mixtures of hydrochloric acid with water and several organic solvents, i.e., dimethylformamide, acetone, tetrahydrofuran, dioxan, methanol, acetic acid and pyndine. Based on these data the conditions most suitable for quantitative separation are indicated and discussed.

摘要

描述了铂族金属和金在盐酸介质中的阴离子交换特性。在强碱性阴离子交换树脂Dowex 1 x 8上，于盐酸与水以及几种有机溶剂（即二甲基甲酰胺、丙酮、四氢呋喃、二氧六环、甲醇、乙酸和吡啶）的混合物中，测定了这些元素的分配系数。基于这些数据，指出并讨论了最适合定量分离的条件。
