| 摘 要： | 本文制备了~(103)Ru标记的Na_2RuNO(NO_2)_4OH]络合物,研究了它在季铵-二甲苯中的萃取性能。分配系数D可达～10~3,萃合物中含2分子季铵。建立了以季铵盐为萃取剂从裂变产物中分离测定~(106)Ru-~(106)Rh的方法,结果与H_2SO_4-NaBiO_3蒸馏法相符。对HNO_3溶解的热铀溶液中钌的化学状态及行为作了初步探讨。

| 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. |
