Anion-exchange behaviour of the platinum metals and gold in hydrochloric acid-organic solvent media.
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.
