Description
In various experimental research studies, scientists have developed and designed new extractants. In this study, a novel extractant named 6-carboxylic di(2-ethylhexyl) amide pyridine (DEHAPA, HA) was developed. It contains three functional groups, namely, carboxylic acid, pyridine, and amide. The extractions of uranium, thorium, and plutonium were determined under different acidic conditions. The results shows that DEHAPA has good extraction abilities for Pu(IV) at 0.5-3 M HNO3. This phenomenon indicates that DEHAPA can be used as a potential extractant in industrial separation process of uranium and plutonium. (author)
