Chemical oxygen demand - Wikipedia

In environmental chemistry, the chemical oxygen demand 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. A COD test can be used to easily quantify the amount of organics in water. The most common application of COD is in …
