FIELD: process engineering.SUBSTANCE: invention relates to electrokinetic decontamination of hard porous medium. Proposed method comprises extraction of contaminants from hard medium to electrolyte, mainly as inorganic gel. Note here that said extraction results from flashing between two electrodes arranged on hard medium surface and/or therein. Note also that contact between at least one of said electrodes and said hard medium is via ply of said gel. It comprises also gel drying. Said gel contains contaminants dried to fragile dry residue to be easily removed.EFFECT: efficient decontamination of cement matrix materials at dismantling of military or industrial structures, particularly, nuclear plants etc, that can be contaminated with ecotoxic chemicals or radioactive substances.15 cl, 9 dwg |
