Abstract:
Improvement on the recovery of palladium from aqueous acidic solutions employing ketoximes, including novel ether oximes and palladium complexes, comprising contacting the aqueous acidic solution containing the palladium with an organic solvent containing the oxime to form two immiscible phases, separating the organic and aqueous acidic phases and stripping the palladium values from the organic phase using an aqueous ammonia solution. The organic phase may contain phase transfer agents and modifiers.
