摘　　要：建立了１个在高盐份强放废液中测定痕量Ｐｕ、Ｎｐ的方法。全程由阴离子交换、ＴＴＡ萃取及电沉积制源３部分组成。对影响测定准确度的关键问题进行了研究。用推荐程序测定了１ＡＷ萃残液中Ｐｕ和Ｎｐ的含量。 radiochemical method for determination of trace neptunium and plutonium in highlevel liquid waste with high level of salt is developed. The analytical procedures involve anion exchange,thenoyltrifluoroacetone (TTA) extraction and electrodeposition steps. The key problems which effect on the accuracy of determination are studied in detail. The amount of plutonium and neptunium in the extractive raffinate of highlevel liquid waste are determinated by using the recommend analytical procedures.
