Preparation of ferrocyanide-anion exchange resin and adsorption test of the prepared resin on the Cs+ ion were performed. Adsorption capability of the prepared resin on the Cs+ ion in the simulated citric acid based soil decontamination waste solution was 4 times greater than that of the commercial cation exchange resin. Adsorption equilibrium of the prepared resin on the Cs+ ion reached within 360 minutes. Adsorption capability on the Cs+ ion became to decrease above the necessary Co2+ ion concentration in the experimental range. Recycling test of the spent ion exchange resin by the successive application of hydrogen peroxide and hydrazine was also performed. It was found that desorption of Cs+ ion from the resin occurred to satisfy the electroneutrality condition without any degradation of the resin.
