摘要
提出了用N-235/聚四氟乙烯柱萃取色层法从铀、镎和镅中分离钚的方法:从2.0mol·l^1 HNO_3溶液中吸附钚,用1.0mol·l^1 HNO_3溶液洗涤,再用HNO_3-H_2C_2O_4溶液洗脱。钚的回收率为97.4±1.8%。
The separation of plutonium from uranium, neptunium and americium is proposed by extraction chromatographic technique. N-235 is used as the stationary phase on polytetrafluoroethylene powder. Plutonium is fixed from 2.0 mol·1^(-1) HNO_3 solution. After washing the column with 1.0 mol·1 HNO_2 solution, plutonium is eluted with a nitric-oxalic acid mixture. The recoveries arc 97.1±1.8%.
