摘要
提出了用N-235/聚四氟乙烯柱萃取色层法自铀、钚、镅和铕中分离镎的方法。镎自2.0mol·lHNO_3溶液中被吸附,用1.0 mol·l^1 HNO_3溶液洗涤后,再用HNO_3-H_2C_2O_4溶液洗脱。镎的回收率为98.1+2.6%。
The separation of neptunium from uranium, plutonium, americium and europium is proposed by extraction chromatographic technique. N-235 is used as the stationary phase on polytetrafluoroethylcue powder. Neptunium is fixed from 2.0 mol·1 ~1HNO_3 solution. After washing the column with 1.0 mol·1 ^(-1)HNO_3 solution, neptunium is eluted with a nitric-oxalic acid mixture. The recoveries are 98.1 ±2.6%.
