PROCESS FOR SEPARATING PLUTONIUM FROM URANIUM
A partition separation method is described in which a solution of U and Pu nitrate in an organic solvent (e.g., dibutylcarbitol, optionally diluted with hydrocarbons) is sent through a column containing a finely divided carrier (e.g., silica gel) which has adsorbed a second solvent that is substantially immiscible with the first one and preferentially dissolves the Pu compound. After passage of the onganic solvent the column is washed out with the organic solvent containing 0.34 M HNO/sub 3/ to remove U and finally eluted with the organic solvent containing 1.15 M HNO/sub 3/ to recover Pu. The first Pu fractions are practically free of fission products. Other solvents and carriers may be used.
