Conclusions

  1. 1.

    The distribution of the components of the ternary system: water-organic solvent-mineral acid between the phase of the cation exchange resin KU-2 and the external solution of the components was studied in methanol, propanol, acetone, dioxane, and dimethylformamide solutions of hydrochloric and nitric acids and in dioxane and dimethylformamide solutions of sulfuric acid.

  2. 2.

    With increasing acid concentration, the selective sorption of water is reduced, while the absorption of the organic component is increased.

  3. 3.

    The sorption of the organic component depends on the thermodynamic and structural properties of the solutions.

  4. 4.

    With increasing concentration of the organic solvent, the selective sorption of water is increased.

  5. 5.

    The presence of a small amount of water causes a sharp asymmetry of the distribution curves.
