Decontamination of radioactive liquid waste with hexacyanoferrate(II)

Takahatake, Yoko  ; Watanabe, So  ; Shibata, Atsuhiro  ; Nomura, Kazunori  ; Koma, Yoshikazu  

Concerning decontamination of a radioactive liquid waste which comprise seawater and nuclides from irradiated fuels and activated materials, the in-situ generation of metal hexacyanoferrates(II) by adding potassium hexacyanoferrate(II) and co-decontamination of $$^{134,137}$$Cs and some activation products were investigated. Transition metals arising from seawater in the waste solution precipitates in the preference order of Zn $$>$$ Ni $$>$$ Co $$>$$ Mn according to their solubility. The precipitate adsorbs $$^{134,137}$$Cs, and decontamination will be attained by the following sedimentation with a polymer and filtration, as an example. Decontamination factor of activated products, $$^{60}$$Co and $$^{54}$$Mn, is dependent on concentration of hexacyanoferrate(II) in the solution.
