摘　　要：用３０％ＴＲＰＯ－煤油直接萃取时，由Ｆｅ（Ⅲ）的大量萃取而引起第三相。研究了利用抗坏血酸还原高放废液中的Ｆｅ（Ⅲ）为Ｆｅ（Ⅱ）的行为，从而减少铁的萃取量，消除ＴＲＰＯ萃取过程中出现的第三相，同时研究了在抗坏血酸存在下，ＴＲＰＯ萃取超铀元素及Ｔｃ的行为。In 30% TRPO-kerosene process, the formation of the third phase in the treatment of present high level waste(HLLW) of China is caused by the extraction of relatively much Fe(Ⅲ). Elimination of the third phase in TRPO process by reduction of Fe(Ⅲ) to Fe(Ⅱ) with ascorbic acid has been studied. Extraction of actinides and Tc with TRPO in the presence of ascorbic acid has also been studied.

关 键 词：第三相 TRPO 抗坏血酸 三价铁 高放废液处理
