Abstract
Considerable synergetic effect has been revealed on extraction of REE(III) ions from chloride solutions with mixtures of picrolonic acid and tris(diarylphosphoryl)-1,3,5-triazines in 1,2-dichloroethane due to formation of hydrophobic mixed-ligand REE(III) complexes. Parameters of extraction equilibrium and 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 been observed in the system with tris(ditolylphosphoryl)-1,3,5-triazine.
