Quantitative studies are repcrted on the cation-exchange behavior of uranium(VI) at the milligram level with Amberlite IR-120. Hydrochloric. nitric. sulfuric. perchloric. acetic. and citric acids were tested as eluants: 200 to 300 ml of 2 N hydrochloric. nitric. or sulfuric acid suffice for quantitative elution of 1.7 mg of uranium(VI) from a 1.4 cm x 14.5 cm bed. The efficiency of the eluting agents is discussed in terms of their elution constants. Uranium is separated from thorium by selective elution. from zirconium. cerium(III), copper. and nickel by converting the latter into suitable anionic complexes, and from phosphate just by passing the mixture through the cation exchanger.
