Аннотация: Considerable synergetic effect has been revealed on extraction of REE(III) ions from chloridesolutions with mixtures of picrolonic acid and tris(diarylphosphoryl)-1,3,5-triazines in 1,2-dichloroethanedue to formation of hydrophobic mixed-ligand REE(III) complexes. Parameters of extraction equilibriumand stoichiometry of resulting complexes have been determined. Effect of aqueous phase composition,organic solvent nature, and extractant structure has been studied. The largest synergetic effect has beenobserved in the system with tris(ditolylphosphoryl)-1,3,5-triazine.
