A long-lived radionuclide, 107Pd, which can be found in radioactive wastes, is one of the difficult to measure nuclides and results in a deficit in experimentally determined contents. In this study, a precipitation based separation method has been developed for the determination of 107Pd with inductively coupled plasma mass spectrometry. The photoreduction induced by pulsed laser irradiation at 355 nm provides short-time and one-step recovery of Pd. The proposed method was validated by applying it to a spent nuclear fuel sample. In order to efficiently recover Pd, a natural Pd standard was employed as the Pd carrier. Taking advantage of the absence of 102Pd in spent nuclear fuel, 102Pd in the Pd carrier was utilized as the internal standard. The chemical yield of Pd was about 90% with virtually no impurities, allowing accurate quantification of 107Pd. The amount of 107Pd in the Pd precipitate was 17.3 ± 0.7 ng, equivalent to 239 ± 9 ng per mg of 238U in the sample.}, pages = {12227--12233}, title = {Determination of 107Pd in Pd Recovered by Laser-Induced Photoreduction for Inductively Coupled Plasma Mass Spectrometry}, volume = {88}, year = {2016} }
