Treatment of clay soils from various contaminations is a difficult task due to their low permeability and high physicochemical affinity to the contaminants. Electrokinetic method in its different variants can be concerned as a perspective technology to treat such soils. Transformations of physical, physicochemical, electrosurface properties, and microstructure of clay soils were studied in the present paper, a new model of electro-osmosis which is considering the recharge of clay soil particles is also presented here. Four clay soils were chosen as the objects of the study: polymineral mantle till loam (Moscow), Glukhovtsy kaolin (Ukraine), Biyasalinian illite clay (Crimea), and Makharadzian smectite clay (Georgia). Physicochemical parameters of soils increase in the row ‘loam-kaolin-illite clay-smectite clay’.
