A liquid-liquid extraction procedure for the separation of greater than 99.8% of uranium(VI) from complex mixtures with one-batch contact is described. It is based on the extraction of tetrapropylammonium uranyl trinitrate with methyl isobutyl ketone from an aciddeficient aluminum nitrate solution. Because 1-yearcooled fission products extract less than 1%, this procedure is especially suitable for separation of uranium from reactor fuel element reprocessing solutions prior to its analytical determination. Per cent extraction for 49 cations at mole ratios of 10 to 1, 1 to 1, and 0.1 to 1 to uranium have been determined. The effects of 30 anions on the extraction of both uranium and fission products have been established. (anth)
