Summary
Data reported in CF-59-11-25 indicated that it was possible to attain thorium decontamination factors greater than 50 in a process employing IM DSBPP (in Solvesso-100) as extractant, an aqueous feed containing 150 g uranium/1, 1.0 g thorium/1, and 1.0N HNO/sub 3/, an aqueous scrubbing solution of 1.0N HNO/sub 3/ , and a flow ratio F/S/O = 1/0.5/1.6. An extension of this data in tests with feeds at 10 g thorium/1 (to increase accuracy of analytical detection) indicates that the thorium DF's are at least 200, and may be several orders of magnitude higher with four to six stages of scrubbing.
