Chemical oxygen demand. In environmental chemistry, the chemical oxygen demand ( COD) is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution. It is commonly expressed in mass of oxygen consumed over volume of solution which in SI units is milligrams per litre ( mg / L ).
Chemical oxygen demand (COD) is an indirect measurement of the amount of organic matter in a sample. With this test, you can measure virtually all organic compounds that can be digested by a digestion reagent. COD contrasts with biochemical oxygen demand (BOD), which relies on the use of microorganisms to break down the organic material in the
