Synergism in the extraction of scandium by a mixture of di-2-ethylhexyl phosphoric acid and a β-diketone has been studied. The nature of the extracted species has been investigated. The effect of temperature on extraction has been studied and synergism has been explained on the basis of thermodynamic parameters of the extraction process.

Synergism in the extraction of cerium in presence of a mixture of a β-diketone and nitrogen donors like pyridine, 2,4-dimethylpyridine, quinoline and 8-nitroquinoline has been investigated. The nature of the extracted species has been investigated and the equilibrium constants for adduct formation have been calculated. Synergism increased in the order 8-nitroquinoline < pyridine ≈ quinoline > 2,4-dimethyl pyridine.

Synergism in the extraction of europium(III) has been investigated using a mixture of naphthoyltrifluoroacetone and synergists like trioctylphosphine-oxide (TOPO), tributylphosphate (TBP), trihexylphosphate (THP), diphenylsulphoxide (DPSO) and benzylsulphoxide (BSO). Synergism decreases in the order: TOPO < TBP ≃THP < BSO < DPSO indicating a correlation between electron density at the donor atom and extent of synergism. The equilibrium constants for adduct formation have also been evaluated.
