Abstract
PURPOSE: To remove excess chlorine ions efficiently, by adding cuporus oxide to the copper sulfate plating liquid and by filtering the plating liquid.
CONSTITUTION: Cuppous oxide is caused to exist in the copper sulfate plating liquid to form insoluble chloride, and the plating liquid is filtered to remove excess chlorine ions in the plating liquid. As a result, unnecessary metallic ions are not accumulated, and the harmful mist accompanied with hydrogen generation is not generated. Further, the brightener is not decomposed, and this method is advantageous to economization.
