METHOD OF WATER PURIFICATION FROM RADIONUCLIDES Russian patent published in 2016 - IPC G21F9/18 

FIELD: chemistry.

SUBSTANCE: in claimed method prepared is nutrient medium for growth of microbiological cultures, deficient by chemical element, corresponding to isotope, which is obtained as a result of transmutation, and which contains necessary for transmutation initial isotope components; microbiological cultures are grown in said nutrient medium. Process of transmutation is realised in three stages, during first of which effect of mutagenic adaptation of contained in biomass microorganisms to particular types of radionuclides is stimulated. Then gradually added are portions of subjected to purification water solution with radionuclides, which do not lead death of biomass due to radioactive irradiation, up to reaching concentration of solution to be purified. Then optimisation of biological part of process of transmutation in obtained solution is carried out. After realisation f transmutation biomass is removed from water to be purified.

EFFECT: creation of conditions in water solution to be purified for nuclear transmutation of radioactive isotopes of some chemical elements into non-radioactive isotopes of other chemical elements in syntrophic associations of microbiological cultures.
