The chemical literature lacks a specific analytic method for adequately monitoring iron in chromium plating and polishing solutions during the plating and polishing processes. In this reports, a specific method is presented for analyzing and monitoring iron during these processes. The optimum operating range of the iron is generally around 10 g1 maximum in both the chromium plating and the polishing solutions. The resulting precisions are in the range of 0.5 to 1.5 g1, providing adequate monitoring of these solutions supported by six years of testing.
