METHOD OF EXTRACTING RADIONUCLIDES AND MICROELEMENTS Russian patent published in 2015 - IPC G21F9/12 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of the sorption technology for the extraction of radionuclides and microelements in processing of various liquid and solid objects of radio-chemical enterprises. The claimed method includes a contact with a sorbent based on transitional metal cyanoferrate, with the contact being realised in a medium of a suspension, which contains humic acid in an amount of 0.15-0.25 g/l relative to the volume of the processed solution or 0.15-0.25 g/dm² relative to the surface of the processed object, with the ratio S_sorb:L not less than 0.001 kg/l.

EFFECT: possibility to increase the degree of purifying polluted objects of the radio-chemical industry from radionuclides and microelements.
