Abstract
In the present study the back extraction of actinoid, lanthanoid, Y, Zr, and Mo from DIDPA [Diisodecylphosphoric Acid] and HDEHP [Di(2-ethylhexylphosphoric) Acid] was investigated by using hydrazine carbonate solution. Hydrazine carbonate is a salt-free reagent and easy to decompose. If it is possible to apply this reagent to the 4-group partitioning process, more sophisticated process would be constructed, because of the reduction of secondary wastes. All the elements other than Y could be back-extracted from HDEHP and all the elements other than Y and Mo could be back-extracted from DIDPA by hydrazine carbonate. It was found that the nature of alcohol which was added to avoid emulsification affects on the distribution ratio more than the added amount. (author)
