Manganese sulfate and potassium hydroxide are added to the sample, forming manganese hydroxide. This reduces the dissolved oxygen, forming a brown precipitate. Alkaline iodide-azide reagent is added to correct for the presence of nitrates found in wastewater samples that can interfere with the oxidation procedure.
