A method is described for the carrier-free separation of microgram quantities of fission product palladium from dissolver solutions of irradiated actinides. The separation is effected by extracting the dimethylglyoxime (DMG) complex with chloroform. This extraction is followed by the destruction of the DMG complex with nitric and perchloric acids. Analysis of the sample is then preformed by surface ionization mass spectrometry using a modified silica gel technique. Radioactive tracers were used to follow the palladium and the most likely mass interferences, ruthenium, silver, and cadmium, through the procedure. A palladium yield of 50-60% and decontamination factors for ruthenium of >4 x 10/sup 4/, for cadmium of >10/sup 4/ and for silver of >10/sup 5/ were obtained at the microgram level. Analysis of several aliquots of a dissolver solution of irradiated /sup 239/Pu demonstrated that the achieved purification was sufficient for mass spectrometric analysis of palladium at the microgram level. 1 figure, 1 table.
