本工作以某高放废液为研究对象,结合阴离子交换法和萃取法,通过一系列条件实验确定了从高放废液中分离出放化纯钚的流程。实验中,先后进行了树脂种类的选择、流速对实验效果的影响、提高钚收率的实验研究、Pu和Np价态的调节实验、钚与TOPO/环己烷中萃取行为的研究和干扰核素的去污研究等条件实验。
In this work, a high level of liquid waste was taken as the research object, and the anion exchange method and extraction method were combined to determine the process of separating and releasing pure plutonium from the high level liquid waste through a series of conditions experiments. In the experiment, the selection of resin type, the effect of flow rate on the experimental effect, the experimental study on improving the plutonium yield, the regulation experiment on the valence of Pu and Np, the extraction behavior on plutonium and TOPO / cyclohexane and the interference nuclei Su-decontamination research and other conditions experiment.
