FIELD: chemistry.SUBSTANCE: invention relates to sorption extraction of caesium radionuclides from aqueous solutions. The method of extracting caesium radionuclides includes filtering an aqueous solution through a selective sorbent which is iron-potassium ferrocyanide on a support, desorption of caesium from the sorbent with an alkaline solution containing Trilon B and potassium oxalate. The eluate obtained from desorption is further filtered through a sorbent which is nickel-potassium ferrocyanide.EFFECT: faster caesium extraction and minimal volume of obtained concentrate containing caesium radionuclides.1 tbl, 2 ex |
