Abstract
The distribution behavior of uranium and thorium has been investigated in a biphasic system of different aqueous nitric acid concentrations and a solu tion of tris(2-ethylhexyl) phosphate (TEHP) in n-dodecane at 25 degrees C. The effect of different uranium and thorium concentrations in the aqueous p hase on the extraction of these metal ions is evaluated. These results indi cate that TEHP is a better choice than tri-n-butyl phosphate (TBP) for the separation of U-233 from the irradiated thorium matrix.
