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 %.
