The article presents the results of the study of the kinetics of ions adsorption from multi-component mixtures. The isotherms of sorption of ammonium nitrogen in the presence of phosphates indicate a decrease in the exchange capacity of zeolite due to its competition for active absorption centres. This study was carried out with two ions of inorganic nature. In the presence of the third organic component in the solution (protein substance - albumin), the sorption capacity of zeolite decreases even more in comparison with ammonium ions. It was found that in the presence of phosphates, the equilibrium capacity of zeolite towards ammonium decreases by about 30%; in the three-component system the reduction reaches about 70%.
