What does COD mean
What does COD mean? What is COD? COD stands for Chemical Oxygen Demand in English and Chemical Oxygen Demand in Chinese. COD is a chemical method used to measure the amount of reducible substances that need to be oxidized in water samples. The oxygen equivalent of substances (usually organic compounds) that can be oxidized by strong oxidants in wastewater, wastewater treatment plant effluent, and polluted water. In the study of river pollution and industrial wastewater properties, as well as the operation and management of wastewater treatment plants, it is an important and quickly measurable organic pollutant parameter, often represented by the symbol COD.
COD rapid analyzer determination method
There are five methods for COD determination: dichromate method, potassium permanganate method, spectrophotometry (chromium method), rapid digestion method, and spectrophotometry (manganese method). The Guan Ao COD rapid analyzer uses spectral breadth (Mn).
Application scenarios of COD analyzer
GA-CODCOD analyzerCan quickly and accurately measure COD in surface water, groundwater, urban sewage, and industrial wastewater, with direct reading of concentration; It can be widely used in sectors such as water plants, food, chemical, metallurgical, environmental protection, and pharmaceutical industries.
