FIELD: chemistry.
SUBSTANCE: invention relates to methods for purification of liquid radioactive wastes from complexions, representing organic compounds, which contain N, S and/or P atoms, capable of coordination of metal ions. Claimed method includes purification of liquid radioactive wastes from complexions by their catalytic oxidation with hydrogen peroxide at low temperatures (20-90°C) in presence of heterogeneous catalysts in form of powder, granules or zeolite applied on porous carriers, based on iron-containing zeolites.
EFFECT: possibility to carry out purification of liquid radioactive wastes from complexions, such as ethylenediaminetetraacetic, oxyethylidenediphosphonic, nitriletrimethylenephosphonic acids, citrates, oxalates, iminodiacetates, nitriletriacetates with degree of conversion of organic compound to inorganic substances in claimed method not less than 40 percent.
