Synergism in the extraction of uranium (VI) has been studied in the presence of a mixture of antipyrine and β-diketones like benzoyltrifluoroacetone, trifluoroacetylacetone and furoyltrifluoroacetone. The nature of the extracted species has been ascertained from the variation of logD with pH and the concentrations of the extractants. The equilibrium constants for the synergistic species have been evaluated taking into account the protonation and partition coefficient of antipyrine.
