The oxygen equivalent of substances (generally organic matter) that can be oxidized by strong oxidants in wastewater, effluent from wastewater treatment plant and polluted water.
Cod is a chemical method to measure the amount of reducing substances that need to be oxidized in water samples. What is cod What does cod mean and what is cod? Full English name of cod: chemical oxygen demand. CODMn is a single fixed wavelength spectrophotometer, which adopt the principle of spectrophotometry to measure the parameters. In the instrument, the linear curves of the concentration of different parameters and the absorbance were established, and the concentration of the water samples was obtained through the identification of the color.It can be used to determine the detection of COD (KMnO4) in drinking water and the concentration is read directly.Widely used in water plant, food, chemical industry, metallurgy, environmental protection and pharmaceutical industry.
