EFFECTS OF GAMMA-IRRADIATION ON COBALT HEXACYANOFERRATE(II) ION-EXCHANGERS

Study was made of the effects of gamma irradiation doses of 2.1 and 5.0 MGy on the structure and cesium ion exchange properties of potassium cobalt hexacyanoferrate(II) and a composite ion exchanger, sodium cobalt hexacyanoferrate(II) in a chelating ion exchange resin in the case of the potassium cobalt hexacyanoferrate only a slight increase in crystal size was observed. The composite exchanger withstood the lower dose, but at the higher dose the organic resin decomposed, leaving a residue of sodium cobalt hexacyanoferrate.
