Determination of Phosphoric and Sulfuric Acids in Polishing Solutions by Acid-Base Titration Using a pH Meter
Abstract
The chemical literature lacks an acceptable analytical method for adequately monitoring phosphoric and sulfuric acids in alloy steel polishing solutions during the polishing process. In this report, an improved method is presented that provides acceptable analysis and monitoring of these acids. The typical operating ranges of these acids constituents are 640 to 730 g/l phosphoric acid and 795 to 895 g/l sulfuric acid. The resulting precisions are in the range of 0 to 8 g/l, providing adequate monitoring of these polishing solutions supported by six years of testing. (EDC)
