Abstract

Based on the stoichiometry of absorption, a thermodynamic approach is proposed for describing the nonexchange sorption of substances with ion exchangers from individual solutions and mixtures. This approach is applied to describe the absorption of amino acids using the sorption of tryptophan and hystidine with anion exchangers AV-17-2P in Cl form as an example. Integral and differential characteristics of nonexchange sorption in these systems are described.
