新型无机复合交换剂磷酸盐-AMP的制备和性能研究

STUDIES ON THE PREPARATION AND PROPERTY OF NEWLY DEVELOPED COMPLEX INORGANIC ION EXCHANGERS.

摘要: <正> 随着原子能事业的发展,利用无机材料从动力堆元件后处理高放废液中提取~(137)CS的工作日益引起人们的重视,而用于提取~(137)Cs的无机材料主要是多价金属磷酸盐和杂多酸盐,但是这两类材料都有不足的地方。我们的工作就是把两种材料结合起来,取长补短,制成了一系列磷酸盐-AMP新型无机复合材料。本文重点研究了这类交换剂的制备,通过反应物浓

Abstract: As an ion exchanger for the recovery 137Cs,some new complex, titanium phosphate-AMP, tin phosphate-AMP and zirconium phosphate-AMP, are prepared by the reaction of phosphates with ammonium molybdate solution. The conditions of synthesis and the ion-exchange properties of the products are investigated. The experiments are also carried out on the recovery of 137Cs from simulation solution of acidic waste, using 1AW as an indicator.
