In the well-known refining processes for platinum group metals (PGMs), Ru is recovered by distillation as RuO4. However, the distillation complicates the processes because of requirements for neutralization, oxidation of Ru, and heating. Although solvent extraction of Ru would result in the simplified refining processes, there has not been any effective extraction systems of Ru. In this study, in order to obtain knowledge for developing efficient extractants for Ru(III), we have investigated Ru(III) species in HCl by X-ray absorption fine structure and UV-Vis spectroscopies, and Ru(III) extraction properties using an amide-containing tertiary amine extractant.
