Chemical oxygen demand - Wikipedia
Chemical oxygen demand - Wikipedia

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.

Stüber believed that ,phenol, could react with carboxylic ,acid, groups on the surface of carbon catalyst to form p-HBZO 20. The generation of p -BZAL originated from the oxidation of p -C 21 . Initially, p -C was oxidized over carbon catalyst in NaOH solution generating p -hydroxybenzyl alcohol ( p -BZOL), and with the further oxidation of p -BZOL, p -BZAL started building up ( Fig. 3 ).
