Chemical Oxygen Demand (COD) is one of the core indicators for assessing the degree of organic pollution in water quality monitoring. It can quickly reflect the total amount of reducing substances (mainly organic matter) in water. It, together with BOD5, constitutes an important basis for judging the biodegradability of water samples and the effectiveness of wastewater treatment processes.
