FIELD: treatment.
SUBSTANCE: invention relates to physical and chemical agents for cleaning and decontamination of contaminated liquid media. Method for electric cleaning and decontamination of contaminated liquids includes electric absorption of contaminants by passing liquid through ferroelectric ceramic filtering granular material 1, placed in sign-constant electric field, and subsequent desorption of filtering material. Granular material used is barium titanate with grain size of 0.1-3.0 mm with non-uniform surface, coated with a copolymer of styrene and divinylbenzene having permittivity comparable with permittivity of filtering material, wherein electric field is switched off during desorption of filtering material.
EFFECT: technical result is higher electrosorption capacity of granular filter material.
