Purifying a nitric acid solution containing U/Pu ions and contaminated by metal impurities by (a) oxidizing the U/Pu ions of the solution to the hexavalent form, (b) conducting the solution after oxidation through a cation exchanger column in which the impurities, especially americium, are retained, (c) flushing the cation exchanger column to remove impurities therefrom, which may be taken to waste processing or utilization plant. |
