STUDY ON REDUCTION OF Fe(III) WITH ASCORBIC ACID IN TRPO PROCESS

Guiming Zhong

Abstract

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.
