FIELD: handling liquid radioactive wastes.
SUBSTANCE: proposed method for recovery of liquid radioactive wastes involves extraction of strontium and cesium radionuclides by means of electrolysis using liquid membrane that has following composition: dibenz-18-kraun-6, 0.36, 3.6 mass percent; trihydrodofluorene heptanol, the rest. Liquid membrane is in immediate contact with aqueous solutions. Aqueous solutions of strontium and cesium salts are used as anolyte and nitric acid solutions, as catholyte, their concentration being 0.2 - 0.4 mole/l.
EFFECT: ability of joint extraction of cesium and strontium radionuclides.
