Each and every of these oxidants is accustomed to determine COD in differing kinds of drinking water: CODMn (COD Manganese) is utilized in determinations for somewhat contaminated bodies of drinking water. In contrast, CODCr (COD Chrome) is used in determinations of seriously contaminated water or wastewater as a result of large oxidizing electric power of your reagent [fifty two, sixty two].

Chemical Oxygen Demand (COD) is defined as the level of oxygen equivalents consumed while in the chemical oxidation of natural and organic make a difference by powerful oxidant (e.g., potassium dichromate). The COD price signifies the amount of oxygen which is necessary to the oxidation of all natural substances in drinking water in mg/l or g/m3.
