The extraction of water, nitric acid, and uranyl nitrate by di-2-ethylhexyl sulfoxide (DEHSO) in dodecane has been measured. Using the program SXLSQA, the data were modeled with correction for nonideality effects (treatments of Hildebrand and Scott and of Pitzer) in terms of the organic-phase species (DEHSO)(H{sub 2}O), (DEHSO){sub 2}(H{sub 2}O), (DEHSO)(HNO{sub 3}), (DEHSO){sub 2}(HNO{sub 3})(H{sub 2}O), (DEHSO)(HNO{sub 3}){sub 2}(H{sub 2}O), and UO{sub 2}(NO{sub 3}){sub 2}(DEHSO){sub 2}(H{sub 2}O){sub w}. 11 refs., 4 figs.
