Cation-exchange behaviour of several elements in nitric acid-organic solvent media.
The cation-exchange behaviour of 19 elements towards the strongly acidic cation-exchange resin Dowex 50-X8 in media containing varying concentrations of organic solvents and aqueous nitric acid is reported. Based on the determination of the distribution coefficients of these elements in the organic solvents methanol, ethanol, n-propanol, isopropanol, methyl glycol, acetone, tetrahydrofuran and acetic acid, the conditions most suitable for their quantitative separation are indicated and discussed.
