CHEMICAL OXYGEN DEMAND (COD) - Real Tech Water
Witryna(a) Underlying Definitions and Concepts: Biochemical oxygen demand (BOD) is an empirical test to provide a measure of the level of degradable organic material in a body of water. 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). A COD … Zobacz więcej The basis for the COD test is that nearly all organic compounds can be fully oxidized to carbon dioxide with a strong oxidizing agent under acidic conditions.
