Theoretical carbonaceous oxygen demand
WebbBiochemical Oxygen Demand (BOD) is a way to measure organic pollution in water by looking at the rate at which micro-organisms in the water use up dissolved oxygen when they metabolize the organic pollutants. For each sample, dissolved oxygen (DO) is tested at the beginning and end of a 5-day, in-the-dark incubation at 20ºC. 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 test can be used to easily quantify the amount of organics in water. The most common application of COD is in quantifying the amount of oxidizable pollutants found in surfac…
