The Chemical Oxygen Demand (COD) is a measure for the amount of oxygen consumed during the oxidation of organic matter, which gives a clear indication for

•COD- Chemical oxygen demand is a measure of oxidizable organic and inorganic material •TOC-Total organic carbon is a measure of organic carbon •Not an exact replacement for BOD/CBOD •Can find trends in BOD/CBOD/COD/TOC of a specific sample using multiple data points over a period of time •No other test provides a better assessment

The determination of Chemical Oxygen Demand (COD) is widely used in municipal and industrial laboratories to measure the overall level of organic contamination in wastewater. The contamination level is determined by measuring the equivalent amount of oxygen required to oxidize organic matter in the sample. See full list on chemetrics.com
