| description | The invention relates to a method for separating strontium ions and barium ions in high-level liquid waste, which comprises the following steps of: preparing an extracting agent: mixing N, N, N ', N'-tetraoctyl-3-oxoglutaramide, tributyl phosphate and a diluent to form the extracting agent; acid adjustment of high-level liquid waste: adding the acid liquid into the high-level liquid waste to adjust the acidity; and extracting and separating: mixing an extracting agent with the high-level liquid waste subjected to acid regulation, carrying out extraction reaction, and completing separation of strontium ions and barium ions in the high-level liquid waste after balance is achieved. Compared with the prior art, strontium and barium ions in the high-level liquid waste can be separated, and the single-stage extraction separation coefficient of strontium to barium ions is larger than 10.
本发明涉及一种高放废液中锶离子与钡离子的分离方法，该方法包括以下步骤：萃取剂配制：将N,N,N′,N′-四辛基-3-氧戊二酰胺、磷酸三丁酯和稀释剂混合，形成萃取剂；高放废液调酸：将酸液加入高放废液中调节酸度；萃取分离：将萃取剂与调酸后的高放废液混合，进行萃取反 |
