Abstract: The sorption of Sc(TII) and Fe(III) ions by a strongly acidic cation exchanger from concentrated solutions of nitric acid and sulfuric acid in aqueous and mixed media (acetic acid and ethanol) was followed. The increased sorption of Sc(III) and Fe(III) from solutions with a high ionic strength and low permittivity is connected mainly with alterations of ionic solvation, the water activity, activity coefficients of the acids, and the increased interaction of ions in the ion-exchanger phase.
