METHOD OF EXTRACTING URANIUM FROM MOTHER LIQUORS

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to method of uranium extraction from mother liquors. Method includes obtaining resin, modified by aminophosphonic groups, and obtaining mother liquor, which contains from 25 to 278 g/l of sulphate and uranium. After that, mother liquor is passed through resin, modified by aminophosphonic groups, in acid form to separate uranium from mother liquor. Then, elution of uranium from resin is realised.;EFFECT: possibility of sorption extraction of uranium from solutions, which contain high concentrations of sulfate.;7 cl, 1 tbl, 3 ex
