  • Process and apparatus for regeneration of chromium plating bath
    Patent number: 6207033
    Abstract: A process for the regeneration of a plating bath comprising trivalent chromium involves the use of platinum anode and a copper cathode wherein the anode to cathode ratio is greater than 2:1 upon passage of a charge having a current density of at least 10 Amperes/diameter2 of exposed cathode. An apparatus for conducting the process is also disclosed. The described process obviates the need for an ion exchange resin and is conducted without the formation of any deleterious toxic sludge.
