Rapid Determination of Chromium in Diamond Tools

Abstract:

This paper draws out a new method to determine the chromium content in diamond tools of metal bond. Used aqua regia to dissolve the sample, perchloric acid emits smoke to oxidize the Cr³⁺ to Cr₂O₇^2- by smoke emission .than used reducing agent of Fe²⁺ standard solution to measure quickly the chromium in the diamond tools of metal bond. This method is verified by quality control chart , this method saves time and practical.
