COD is the preferred different test to BOD for establishing the focus of organic issue in wastewater samples.
This oxidation is catalyzed by silver sulfate. The catalyst is needed, Primarily to oxidize reduced molecular body weight fatty acids. The oxidation because of the acidified dichromate might be represented by the subsequent equation:
The dichromate technique is really a broadly made use of approach for measuring COD. It involves introducing a recognized extra of potassium dichromate to your recognized quantity of sample within the presence of sulfuric acid.
Chemical Oxygen Demand can be a crucial metric from the wastewater sector and is often described as milligrams of oxygen consumed for every liter of sample (mg/L COD).
