Abstract

The influence of acidity of aqueous solutions of methionine on their interaction with carboxyl cationites in the copper form was studied by the calorimetric, sorption, and spectroscopic methods. The distribution of methionine between aqueous solutions and sorbents with the formation of Cu(II) cation complexes in both phases was observed over the pH range 5–12. The enthalpies of interaction between methionine and KB-2 and Kb-4 cationites in the copper form were determined at various pH.
