title: Cation-exchange behaviour of several elements in hydrofluoric acid-organic solvent media.
abstract: The cation-exchange characteristics of 15 elements with the strongly acidic cation-exchange resin Dowex 50 x 8 were investigated in media containing varying concentrations of organic solvents and aqueous hydrofluoric acid. The determination of the distribution coefficients was carried out in 0.15-1.2 M hydrofluoric acid solutions containing 0-90% of the organic solvents methanol, ethanol, n-propanol, isopropanol, methyl glycol, acetone, tetrahydrofuran, and acetic acid. Based on these distribution data the possibilities of separations of the various elements are indicated and discussed.
