Chemical Oxygen Demand (COD) Notes:

The Chemical Oxygen Demand (COD), in environmental chemistry, is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution. Commonly expressed in SI units mg/L (mass of oxygen per liter). A Chemical oxygen test can be used to determine the amount of organics in water. Its most common and useful application is determination of water quality by providing a metric to determine the effect of an effluent on the receiving body, much like Biochemical oxygen demand (BOD).
