Cation-exchange behaviour of several elements in hydrochloric acid-organic solvent media.
In the present paper the cation-exchange characteristics of 20 elements towards the strongly acidic cation-exchange resin Dowex 50 X 8 in media containing varying concentrations of organic solvents and aqueous hydrochloric acid were investigated. 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.
