Abstract

The partition of uranium(VI) between nitric acid and N,N-dibutyldecanamide (DBDEA) in kerosene has been investigated at various concentrations of nitric acid, extractant and salting-out agent LiNO3. The mechanism of extraction is discussed in the light of the results obtained. The effect of TBP on the extraction of uranium(VI) with DBDEA has also been considered. There is an apparent synergistic effect with these two extractants at low concentration of TBP, however, one sees a decrease in extraction distribution at higher concentration. IR spectra show that there is no apparent interaction between the two kinds of extractants. The stoichiometry of the synergistic extracted species has been determined.
