The protection, utilization and research of water resources have become one of the hottest topics in the world today. Chemical oxygen demand (COD) is a chemical method to measure the amount of reducing substances that need to be oxidized in a water sample. It is the oxygen equivalent of substances that can be oxidized by strong oxidants in wastewater, effluent from wastewater treatment plants and contaminated water. In the study of river pollution and the properties of industrial wastewater, as well as the operation and management of wastewater treatment plants, it is an important and quickly measured organic pollution parameter, often represented by the symbol COD.
