Highly selective separation of individual platinum group metals (Pd, Pt, Rh) from acidic chloride media using phosphonium-based ionic liquid in aromatic diluent

An effective solvent extraction-based method has been developed to recover individually platinum group metals (Pd, Pt, and Rh) with high purity from acidic chloride media using phosphonium-based ionic liquid Cyphos IL 101 in aromatic solvent.
