Abstract
103Ru-labeled Na2Ru(NO2)4OH complex is prepard and its extractive properties studied in quaternary ammonium-xylene. Distribution cofficients are as high as 103. There are two molecules of quaternary ammonium in the extraction complex. The behaviour and states of ruthenium in the nitric acid solution of irradiated nuclear fuels are investigated. The method of separation and determination of ruthenium in fission products with quaternary ammonium extraction is established. The specific activity of ruthenium in the nuclear fuels is in agreement with the value measured by distilling ruthenium with H2SO4-NaBiO3.
