Cations that may commonly be present in chromium plating baths include chromium (III), iron, copper, nickel, zinc and sodium. Chromium (III) usually result when baths are operated with too large a cathode area and too small an anode area or when organic matter is introduced. The chromium (III) content can be kept down by increasing the area of the lead anodes used relative to the cathode area, or, where this is not practical, by electrolysis the solution for a time with a relatively large anode area and a small cathode area.
