Cation-exchange behaviour of several elements in hydrobromic acid-organic solvent media.
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.
