Abstract
A recovery system for platinum electrolytic baths operating at low current densities is disclosed. An oxidizing system is provided in a closed-loop recirculation system for platinum plating at low current densities. The oxidizing system reoxidizes Ptions, which are typically formed at low current densities, to Ptions by using oxidizers, for example peroxide. A sensor may be also provided to detect the relative concentration of [Pt] ions to [Pt] ions and to tailor the relative concentrations to a predetermined level.
