Abstract
Data from published and unpublished sources on electrolytic removal of small quantities of copper, zinc, and iron from nickel‐plating baths have been compared. As expected the more noble copper plates out preferentially at a rate limited only by diffusion to the cathode. Zinc ions increase the cathodic potential for nickel deposition to the point that zinc plates out with nickel at a diffusion‐limited rate. Removal of iron may also be diffusion limited but results are less clear than for copper and zinc.
