摘要: 本文研究了5种有机溶剂对铀(Ⅵ)和铁(Ⅲ)在盐酸溶液和201×7型阴离子交换树脂间分配行为的影响。结果表明,不同有机溶剂对这两种离子的交换行为的影响有明显不同,在盐酸溶液中加入适当的有机溶剂可使铀(Ⅵ)和铁(Ⅲ)在阴离子交换柱上定量分离。Abstract: The effects of five kinds of organic solvents on the distributions of uranium (Ⅵ) and iron (Ⅲ) between anion exchange resin-201×7 and hydrochloric acid solutions are investigated.The results show that the effects of different organic solvents on the ion exchange behavior of the two ions vary significantly. So uranium (Ⅵ) and iron(Ⅲ) can be separated conveniently and quantitatively on anion exchange column by adding a proper amount of organic solvents in the hydrochloric acid solution.
