 Objects of research - electrolyte solutions, membrane, diluted and concentrated disperse systems. The aim of the work is to develop physicochemical models and experimental study of polarization and electrokinetic processes in membrane, dilute and concentrated disperse systems. The purpose of the work is to conduct basic research aimed at studying the laws of transport of particles and ions in the hydrodynamic and electric field in the application to the practical problems of water and dispersion decontamination using an electric field. Research methods - methods of analytical chemistry, electrochemistry and mathematical physics. Theoretical and experimental researches of electric transport processes in systems created with the use of ion-exchange materials and natural minerals has been carried out. The electrocatalytic activity of electrodes in the oxidation of organic impurities and water disinfection has been studied. Theoretical and experimental investigations and comparison of polarization processes in stationary and periodic electric and hydrodynamic fields are carried out. The complex influence of chemical and physical factors on the dehydration of clay dispersions and their decontamination from heavy metals and uncharged organic compounds has been studied. Adsorption-desorption processes on natural dispersed particles and catalysts have been studied. The obtained results are important for the development of the fundamental bases of processes in membrane and disperse systems in application to water and soil decontamination technologies.
