  • Purification of nickel and cobalt electroplating solutions
    Patent number: 4053400
    Abstract: Zinc, copper and/or iron impurities ordinarily associated with nickel or cobalt electroplating baths can be removed from solution by introducing an amount of a predetermined and selected alkylthiuram sulfide compound into the electroplating bath sufficient to convert the zinc, copper and/or iron impurities into relatively insoluble metal salts. The insoluble salts may then be removed from the bath by passing the treated solution through a standard filtering system.
