PROCESS OF DECONTAMINATION OF SOLUTIONS FROM RADIONUCLIDES Russian patent published in 1995 - IPC

FIELD: nuclear power engineering. SUBSTANCE: process refers to decontamination of liquid radioactive waste. Solution carrying radionuclides is passed in series through two sorbents. First sorbent presents industrial ferrocianide sorbent based on in organic carrier type НЖА or Selex -ЦФК or МЖА or Selex-ЦФМ. Second sorbent is zeolite of A type of hydroxide of tetravalent metal in which capacity hydroxide of circonium, titanium or manganese is used. Hydroxide in this case can contain inert binders in addition. EFFECT: high degree of decontamination of solution from radionuclides of Cs and Sr with high values of volumes of solution passed through sorbents. 3 cl, 2 tbl
