What should I do if carbonization occurs during wet digestion?

Wet digestion is to add oxidizing strong acid to a proper amount of food, and at the same time heat and digest it to destroy the organic matter in the food. Among them, sulfuric acid has strong dehydration ability and can carbonize organic matter. You can add a few drops of nitric acid to change the color back and try to avoid carbonization.

Wet digestion is a method of destroying organic or reducing substances in samples with acid or alkali solution under heating conditions.
