A stripping methcd for the amine extraction (Amex) process, ;involving treatment of the U-loaded extract with 4 with NH/sub 4/OH, was demonstrated in continuous equipment. The steady-state distribution losses of 1- nonyldecylaimine, 1-undecyllaurylamine, bis(l-heptyloctyl) amine, bis(lnonyldecyl) amine, N-benzyl-1-nonyldecylamine, and N-benzyl-1- undecyllaurylamine were all less than 5 ppm to typical ore leach liquor. A tentative process for recovery of strontium from Purex 1-WW solutions by di(2 ethylhexyl) phosphoric acid was demonstrated with synthetic solutions in a laboratory pulse column. Batch countercurrent laboratory studies of a promising and relatively radiation-stable U -Pu extraction reagent are reported. The amine extraction of Th was studied. (W. L.H.)
