SEPARATION OF THORIUM FROM URANIUM BY SELECTIVE STRIPPING FROM DIBUTYL CARBITOL

OSTI ID:4242597
An approach to the problem of separating thorium from uranium in Solvent extraction process streams is described. Aqueous phosphate, oxalate, and fluoride scrub systems were compared for their ability to remove thorium from dibutyl carbitol which contained both thorium and uranium. A mixer-settler apparatus was employed for contacting aqueous and organic phases. Thorium decontamination results obtained with the use of a phosphate scrub were not encouraging. Both oxalate and fluoride scrub systems gave satisfactory results. The fluoride system was selected for application because of the relatively high decontamination factors obtained, the ease of maintaining a suitable concentration of fluoride ion, and the facility with which thorium fluo ride can be isolated from the spent scrub solution.
