Radiochemical Application of “Iron Ferrocyanide-Anion Exchange Resin”

Preparation of iron ferrocyanide-anion exchange resin and adsorption of 137Cs on the resin are described. The resin was found to effectively adsorb 137Cs from concentrated nitric acid solution, contrast to the negative results previously obtained with copper ferrocyanide-anion exchange resin. A discussion is given of the possibility of applying the iron resin to the removal of 137Cs from fuel reprocessing waste solution. Fission products were effectively separated from each other with a column of this resin, utilizing the properties possessed by it of both iron ferrocyanide and the parent ion exchange resin.
