The partition of uranium(VI) between nitric acid and N,N diethyldecanamide, C 9H 19 CON(C 2H 5) 2, (DEDEA) in kerosene has been investigated at various concentrations of nitric acid, extractant and salting out agent LiNO 3. The mechanism of extraction is discussed in the light of the results obtained. The effect of TBP on the extraction of uranium(VI) with DEDEA has also been considered. There is apparent synergism between these two extractants at low concentration of TBP; however, at higher concentration, distribution ratio decreases.
