Blank = 0 mg/L Standard = 385 mg/L Sample waste = 23 mg/L Discussion The Chemical Oxygen Demand (COD) test is used widely to estimate the amount of organic matter in wastewater. It is a measurement of the oxygen equivalent of the materials present in the wastewater that are subject to oxidation by a strong chemical oxidant, in this case, dichromate.
