Reversed-phase partition chromatography is shown to be a convenient and effective method for the quantitative recovery of microgram to gram quantities of uranium from highly impure solutions of unknown composition. The uranium is obtained in a form suitable for determination by a volumetric, colorimetric, or alpha -counting technique. Uranium is retained by a column of Kel-F supporting tri-n-butyl phosphate. Impurities are eluted with 5.5M nitric acid, and the uranium is eluted with water. Thorium(IV), plutonium (IV), and cerium(IV) intenfere, but interference by cerium can be avoided by reduction to cerium(III) prior to separation. Recovery of uranium is better than 99%. The method can be adapted to the separation of uranium and plutonium. (auth)
