SORPTION METHOD FOR CLEANING SOLUTION FROM RADIONUCLIDES Russian patent published in 1997 - IPC

Abstract RU 2088985 C1

FIELD: treatment of materials contaminated with radioactive pollutants, such as decontaminating water solutions by sorption method. SUBSTANCE: method involves sequential passage of contaminated solution through inorganic sorbent layer based on ferrocyanide of intermediate metal, through cation- and anion-exchange resins. Nickel (II) or copper (II) is used in most cases as intermediate metal. EFFECT: improved cleaning of solutions from radionuclides, enlarged service life of ion-exchange resins, improved selectivity of radio nuclide extraction from water while keeping stable components in water. 2 cl, 1 tbl
