Abstract:

The chemical literature lacks a simple non-instrumental analytical method to determine and adequately monitor trivalent chromium in chromium plating solutions during the chromium plating process. In this report, a simple method for analyzing and monitoring trivalent chromium during the chromium plating process is presented. The optimum operating range of trivalent chromium is 0 to 7.5 g1, and the resulting precisions are in the 0 to 1.5-g1 range, providing adequate monitoring of these plating solutions supported by five years of testing.
