The objects of investigations are the diluted aqueous dispersions and electrolyte solutions, concentrated dispersion systems, metal-oxide anodes. The aim of the work is the development of electrochemical methods of removal of charged and non-charged admixture from disperse systems, investigation of conditions of formation and electrocatalytical activity of metal-oxide anodes. The method of investigations - the method of analytical chemistry and electrochemistry, methods of mathematical physics, microelectrophoresis, optical microscopy, thermochemistry. The main results are: Theoretical and experimental research of dewatering of model systems showed that there is a wide range of pH of the pore solution, when electroosmosis velocity reaches maximum values, creating optimal conditions for dispersion dewatering at the application both using external electric field and pressure. The decontamination of a clay soil from ortohlortoluol using different surfactants was carried out. It is shown that the most effective way to remove the admixture is achieved by using Neonol AF-9-12. The characteristics of platinum and titanium anodes coated with nanoheterogenic films are analyzed. It is shown that according to the electrocatalytic and economic characteristics the most promising for hypochlorite installations is cobalt oxide anode on the titanium basis. The research and the main regularities of influence of silicon domestic deposits on cleaning and mineralization of drinking water are carried out. The results are important for the development of fundamental knowledge about the properties of disperse systems and can be used to create new technologies in water purification. Scope - water treatment.
