The distributions of cesium and strontium between a synthetic fission product solution in 3M HNO/sub 3/ and a matrix solution of dinonylnaphthalene sulfonic acid (NNS), tributylphosphate (TBP), and kerosene containing crown compounds were studied. The distribution coefficients (org/aq) of all fifteen fission products were measured between 3M HNO/sub 3/ and an equal volume of 5 vol % NNS, 27 vol % TBP, and 68 vol % kerosene containing one of several crown compounds of varying molarity. Bis 4,4'(5')(1-hydroxyheptyl)cyclohexo 18-crown-6 (Crown XVI) was the most effective crown compound in strontium extraction. A 0.02M Crown XVI solution extracted strontium (initially 0.003M Sr+/sup 2/) from the synthetic fission product solution with a distribution coefficient of 1.98. Bis 4,4'(5')(1-hydroxy2-ethylhexyl)benzo 18-crown-6 (Crown XVII) was the most effective crown in cesium extraction. A 0.05M Crown XVII solution extracted cesium (initially 0.006M Cs/sup +/) from the synthetic fission product solution with a distribution coefficient of 1.59. Distribution coefficients of both cesium and strontium decreased from 1.59 to 1.04 and from 1.98 to 1.56, respectively, as the system exposure was increased to 1.0 x 10/sup 7/ rad in a 0.4 x 10/sup 7/ rad/h source. Zirconium was extractable by the NNS, TBP, kerosene matrix solution alone and extractable to a lesser extent when Crown XVI or Crown XVII was present in the matrix solution. As the system exposure to gamma radiation was increased, the distribution coefficient of zirconium increased from about 2.0 to about 3.0 depending on the organic phase under study.
