Mixed chelates of hafnium in benzene medium was studied by the method of solvent extraction. Various β-diketones and their mixtures were used for the study. The equilibrium constants for the mixed complexes were evaluated. Synergism in the extraction of hafnium in the presence of two dissimilar acidic extractants viz. HDEHP and a β-diketone was also investigated. The stoichiometry of the extracted species was determined by graphical method.
