STUDIES ON THE EXTRACTION OF Ru(IV) WITH MIXED SOLVENTS

In this paper, both the diluent effect of diluents with different dielectric constant in the extraction of Ru(IV) with TOA and the extraction mechanism of Ru(IV) mixed solvent TOA + TBP(CB type), TOA+TTA, TOA + PMBP (CA type) in 4 mol/l HCl media are reported.Weak synergistic extraction effect of Ru(IV) is observed in the system with 0.060 mol/1 (TOA +φ4 AsCl) (CC type) . The synergistic extraction coefficient is found to be R = 1.04.
