Chemical oxygen demand (COD) is definitely an oblique measurement of the level of natural and organic subject in a very sample. With testing COD, you'll be able to evaluate practically all natural and organic compounds which might be digested by a digestion reagent.
COD is actually a vital indicator of h2o high-quality and it is used in many different programs, such as the subsequent:

The test entails using hazardous chemicals that have to be disposed of correctly and should represent a threat on the operators.
Divide the COD focus because of the BOD concentration for every sample and normal the outcome. As an example, below is definitely the COD:BOD ratio formulated employing three wastewater samples from the foods processor:
It may be described as the quantity of oxygen required by natural and organic subject within a sample of h2o for its oxidation by a powerful oxidizing agent and is expressed as ppm of oxygen taken from an answer of K2Cr2O7 in two sorts.
