Precise rapid tests for water and waste water samples
The chemical oxygen demand (COD) is one of the most important parameters for the assessment of industrial and municipal wastewater. As a cumulative parameter, COD determines all chemically oxidizable components present in water. Hence, this includes not only biodegradable substances (as in the BOD5), but also chemical compounds that cannot be determined by biological oxidation (e.g. nitrogen compounds such as nitrites). It has also the advantage of a faster availability compared to BOD.
The COD indicates the contamination of a water sample. It is therefore also used as an evaluation parameter to determine pollution units in discharges under the German Wastewater Charges Act.
By definition (ISO 15705), the COD is the concentration of oxygen that is equivalent to the mass of potassium dichromate that is consumed in total oxidation of organic substances present in the water sample. Mercury sulfate and silver sulfate as well as sulfuric acid are listed as auxiliary reagents.
Did you know?
The COD covers all oxidizable contents of the sample.
