Description
A simple radiochemical method is described for separating indium-114 from cadmium and copper. The separation is carried out by the difference in the sorption of indium, cadmium and copper on an organic or an inorganic cation exchanger (Dowex 50 X 8 or potassium zinc hexacyanoferrate, respectively) from 0.05 or 10-5M HCl, respectively. The distribution coefficients of the three elements on two types of cation exchangers were evaluated in HCl (0.05 or 105M), acetate buffer (1M) at Ph 4 and EDTA (103M) in order to find the best conditions for separation of 114Indium from Cd and Cu. A comparison of the separation by these cation exchangers shows one suitable cation exchanger (Dowex 50 X 8) with radiochemical separation yield of radio indium more than 98% within 50 min by using column chromatograph
