Abstract

The use of the isotope-dilution mass spectrometry for the determination of mg amounts of Pu is described. A solution of the NBS-Pu-949f standard reference material was used as the spike. The optimum spiking conditions have been calculated on the basis of the measured isotope composition of the spike and the sample. The isotope exchange was achieved by a reduction /NH2OHHCl/ oxidation /NaNO2/ cycle. Plutonium was separated from the solution by TTA extraction. The isotope composition of Pu was measured with the aid of a MAT-261 mass spectrometer. The average error of the Pu determination for samples containing 4 mg Pu was <0.1 rel%.
