1AF溶液是后处理Purex流程中一循环的进料液,1AF中各组分的含量对整个Purex流程都有影响。1AF中铀、镎和钚的含量分析对掌控工艺运行状态有重要意义。目前国内对1AF中铀和钚的含量分析主要采用混合K边界密度计直接测定,而对于镎,由于其含量低,铀、钚含量及放射性水平高,其测定一直是未能解决的问题。为此,建立了TEVA萃取色层分离1AF样品中镎的方 The 1AF solution is a recycled feed solution in the post-treatment Purex process, and the content of each component in 1AF affects the entire Purex process. The analysis of the content of uranium, gallium and plutonium in 1AF is of great significance for controlling the operation of the process. At present, the content of uranium and plutonium in 1AF is mainly determined directly by the mixed K boundary densitometry, while the determination of 镎 due to its low content, uranium, plutonium and radioactive levels has been an unsolved problem. To this end, established TEVA extraction chromatography color separation 1AF sample Fang side
