A paper chromatographic technique has been adopted to separate UO2(II) from Th(IV), Ce(III), Fe(III) and Zr(IV) in binary and ternary combinations using a solvent consisting of chloro­form acetone-amyl alcohol and concentrated hydrochloric acid (12:6:6:1v/v). A direct photodens­itometric method of evaluating unknown quantitatively from strips run simultaneously for known and unknown has been described, which proved better in comparison to other known methods of direct spot evaluation. The procedure appears to be useful for estimating UO₂(II) within concen­tration range < 50 µg.
