“…The uranium and plutonium in a nuclear fuel sample can be simultaneously determined by a-spectrometry, 3 spectrophotometry, [4][5][6][7] thermal ionization mass spectrometry, 8 neutron activation analysis, 9 potentiometry 10 etc. Redox titration methods, employing a visual indicator or electrometric end point detection, are widely used for the determination of uranium and plutonium independently in the uranium-plutonium mixed oxides.…”
