摘要
用硫酸淋洗载铀树脂所得的合格液,来考察在不同渗析条件下聚醚型阴离子交换膜的静态和动态行为,及影响渗析传质的有关因素。初步试验表明,扩散渗析可以用来分离回收其中大部分的硫酸,从而降低溶液的酸度,减少沉淀产品的碱耗。
The static and dynamic state dialysis behaviors of polyether ion exchange membrane are studied under different dialysis conditions in the solutions of eluting uranium from the loaded resin with sulfuric acid. Some factors influencing the dialysis coefficient are investigated. Preliminary test indicates that most of sulfuric acid can be separated and recovered by diffusing dialysis process. Consequently, the alkali consumption is reduced in uranium precipitation process.
