FIELD: decontaminating liquid radioactive wastes.
SUBSTANCE: proposed method for decontaminating liquid radioactive wastes incorporating permanganate-ions includes recovery of the latter and separation of manganese dioxide in alkali medium accompanied by deposition of radionuclides thereon. Recovery of permanganate-ions in alkali medium is conducted by electrochemical method using single-chamber electrolyzer at current densities of 10 - 500 A/m2. Oxalate-ions are introduced in advance into solution to be decontaminated. Radioactive wastes incorporating oxalic acid may be introduced in solution to be recovered.
EFFECT: enhanced effectiveness of radioactive waste decontamination.
