Abstract

Thermodynamic constants of ion-exchange equilibria for Cr 3+ and Ni 2+ ions on sorbents obtained on the basis of Na-forms of synthetic and natural sorbents using the Tolmachev and Gorshkov equations are calculated in the article. The values of free energy and other thermodynamic parameters are calculated on the basis of these data.
