Determination of Iron in Chromium Plating and Polishing Solutions by Atomic Absorption Spectrometry.

摘要

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 g/1 maximum in both the chromium plating and the polishing solutions. The resulting precisions are in the range of 0.5 to 1.5 g/1, providing adequate monitoring of these solutions supported by six years of testing.
