Purpose of Hydrogen Peroxide with the Digesdahl®
Answer
Hydrogen Peroxide reacts with Sulfuric acid at the digestion temperature to form Peroxy-monosulfuric acid (H2SO5) which is an extremely powerful oxidizing agent toward carbonaceous material. The objective is to maintain an adequate concentration of H2SO5 during the digestion to complete oxidation of carbonaceous material.
