Extraction of silver and palladium metals from aqueous solutions using tertiary phosphine sulfides |
摘要 |
Silver or palladium metals are selectively extracted from aqueous sulfuric acid solution by contacting the solution with a water-immiscible organic solvent extraction solution comprising a tertiary phosphine sulfide compound; separating the resulting silver- or palladium- phosphine sulfide complex from the aqueous solution; and recovering the silver or palladium metal from the complex by suitable stripping means.
