The complex-forming properties of polycomplexons including ions of amino and amino- phosphon groups obtained on the basis of local raw materials with Cu (II), Ni (II), Co (II), Zn (II) and Cr (III) were analyzed. The process of sorption of metal ions into ion exchangers was studied in the Pseudo-First-Order and PseudoSecond-Order kinetic models, and it was determined by studying the absorption kinetics that the sorption process was the Pseudo-Second-Order Kinetic Model. The Langmuir and Freundlich constants of the isotherm of absorption of Zn (II) and Cr (III) ions into anion exchange resin and polyampholyte at different temperatures were calculated. Based on the results of the study, the thermodynamic parameters of the sorption process, the isothermal-isobaric potentials, the changes in the values of free energy (ΔG), enthalpy (ΔН) and entropy (ΔS) were found by calculating.
