Abstract
A method stops the preparation of an electrolytic chromium deposition bath, which comprises reacting an aqueous trivalent chromium electrolyte with at least 30 parts per million of an iron salt and/or a nickel salt and, if the total amount of iron and nickel exceeds 150 parts per million to react any excess over 150 parts per million with sufficient potassium ferrocyanide to reduce the concentration of iron and nickel to a value within the range of 30 to 150 parts per million.
