Spectrochemical determination of tantalum in plutonium metal using direct current plasma emission spectrometry

OSTI ID:5484018
Tantalum is determined by direct current plasma spectrometry after separation of plutonium from solution as PuF/sub 3/. After centrifugation of the PuF/sub 3/ precipitate, a low level of plutonium remains in solution in sufficient quantity to cause spectral interferences. It is necessary to determine the plutonium by dc plasma spectrometry and apply a correction to determine low tantalum concentrations with good accuracy and precision. Tantalum can be determined down to 0.4 ppM in solution with a relative standard deviation of 10 percent. Better precision can be achieved at higher concentrations. The procedure is simple and convenient for glovebox work. 5 references, 1 figure, 1 table.
