Application of Acetohydroximic Acid in the Simplification of TRPO Process

Song Chongli

Abstract

The simplification of the stripping steps of TRPO process by using acetohydroximic acid is studied. Am(Ⅲ), RE(Ⅲ) and Pu(Ⅳ) loaded on 30% TRPO/kerosene can be stripped by 0.5 mol/L acetohydroximic acid, while U(Ⅵ) can not be stripped, thus U can be separated from Am and Pu. However, it is difficult to strip Fe(Ⅲ) from the loaded extractant, this will cause trouble to the U stripping with 50 g/L ammonium carbonate or sodium carbonate. Therefore, to use acetohydroximic acid in simplification of TRPO process, the problem of stripping of Fe must be solved.
