摘要
合成六种有离子交换性能的焦磷杂多酸盐 ,其中焦磷钼酸锆在 3M硝酸介质中有较高的化学稳定性和铯离子交换容量。经正交实验确定了合成焦磷钼酸锆的最佳工艺条件。以焦磷钼酸锆为基体 ,通过特殊的化学制筛手段 ,制成了对铯离子有高效选择性、抗强酸的提铯离子筛 ,可适用于直接从高放废液中提取铯。
Six kinds of pyrophosphate are synthesized.The investigation of ion exchange properties demonstrates that zireony molybopyrophosphate (ZMPP)exhibits high chemical stability and exchange capacity for cesium in the 3mol HNO 3.The optimum synthesis conditions of ZMPP are determined by orthogonal experiment.With ZMPP as a matrix,a new functional environmental material Cesium Ion-Sieve (Cs-IS) is developed by special chemical sieve-making means.It can directly and effectively remove and recover Cs from HLLW.
