The aim of the study is to research of the adsorption properties of heavy metal ions Pb2+, Cd2+ and Ni2+ from industrial wastewater. For the adsorption of heavy metal ions, natural clinoptilolite was used, which belongs to the Ai-Dag deposit of the Tovuz-Kazakh region of Azerbaijan. Isotherms and kinetic curves of adsorption of heavy metal ions Pb2+, Cd2+ and Ni2+ were determined. The dependence of the adsorption of heavy metal ions on the pH value is also shown. It was revealed that the separation process proceeds more intensively at pH values of 5-6. It has been established that the maximum adsorption capacity of the clinoptilolite adsorbent for the adsorption of Pb2+, Cd2+, and Ni2+ ions is 7.5, 6.7, and 5.9 mmol/g, respectively.
