Wet digestion and differential pulse stripping voltammetry determination of total chromium in the millet
The chromium content of millet is measured by HNO3-H2O2 digestion and electrochemical method. In the DTPA-HAc-NaAc system, the oxidation peak current of amalgam formed by hexavalent chrome ion is obtained in the plating mercury electrode, and the pre-treatment technology of wet digestion can meet th...
