Separation of U from irradiated ThO/sub 2/-Th(CO/sub 3/)/sub 2/ is accomplished using sodium diethyldithiocarbamate. The irradiated material is dissolved in HNO/sub 3/ and brought to a pH of 2 or 3. The sodium diethyldithiocarbamate is dissolved in annyl acetate to make a 0.25% solution which is contacted with the nitrate solu tion. The U forms a diethyldithiocarbarnate salt which remains in the organic phase to the exclusion of Th and Pa. If an organic solvent such as methyl isobutyl ketone is used, some Th is extracted into the organic phase. (T.R.H.)
