An extraction, spectrophotometric procedure was developed specific for the determination of large quantities of uranium in the presence of molar concentrations of diverse ions. The method is based on the quantitative extraction of tetrapropylammonium uranyl trinitrate with methyl isobutyl ketone from an acid deficient aluminum nitrate salting solution, followed by a direct absorbance reading of the organic phase at 452 m mu . The molar absorptivity at this wave length is 31.4. The coefficient of variation is O.71% at the 10-mg level. The method is simple and rapid. The uniqueness of the spectrum is useful as a qualitative indication of uranium and as a means for readily observing interferences. (auth)
