摘　　要：观察了用ＴＲＰＯ萃取法直接处理我国生产堆高放废液产生第三相的情况，研究了稀释法和加入添加剂对形成三相及以镅为代表的锕系元素的萃取能力的影响，对ＴＢＰ－ＴＲＰＯ－煤油萃取体系进行了辐照稳定性研究。The formation of the third phase in the treatment of high level waste by TRPO extractionhas been observed.The influence of diluting the feed solution and intreducing additives to the or-ganic solution on thc formation of the third phase and the extraction coefficient of Am have beenstudied.The radiation stability of TBP-TRPO-kerosene has been tested.
