A spectrophotometric extraction method for milligram levels of plutonium is described. Following a silver (II) oxidation, plutonium(VI) as the tetrapropylammonium trinitrate complex is extracted quantitatively into methyl isobutyl ketone from an acid-deficient aluminum nitrate salting solution. Though uranium and neptunium are extracted also, their spectra are sufficiently discrete so that a direct absorbance measurement of the separated organic phase can be made for plutonium in the presence of the other two actinides. The method is fast, gives excellent decontamination from fission product nuclides, and is virtually free of diverse ion interference. It is applicable to the range of 2.0 to 15 mg of plutonium with a 0.3% standard deviation of the 12.3-mg level, comparing favorably with redox titrimetric and coulometric methods. A method for the simultaneous determination of plutonium and uranium is described. (auth)
