Abstract
The adsorption and desorption of 137Cs on copper ferrocyanide-anion exchange resin, prepared in the manner previously reported in this Journal in a Short Note, are presented in detail. This resin can also be used for the concentration of the 137Cs found in sea water. The nuclide is adsorbed effectively on the resin from water, hydrochloric acid below 4 M, and on nitric acid below 1M. After adsorpsion on the resin, 137Cs is eluted easily with either nitric acid (>6M), ammonium water, or silver nitrate solution. Adsorption on the resin is specific for 137Cs, and the action is due entirely to the ferrocyanide moiety of the resin. This method is more efficient than the co-precipitation method with copper ferrocyanide for the concentration of radiocesium from a large volume of sea water.Keywords
