chemical oxygen demand vials Chrominex

Apr 02, 2021 · BOD stands for Biochemical Oxygen Demand, is the amount of oxygen required for bacteria to decompose biodegradable organic matter at certain temperature for a specific period of time. It is used mainly in determination of pollution strength of water in terms of requirement of oxygen, when this wastewater is discharged into water bodies.

The chemical oxygen demand (COD) test is commonly used to indirectly measure the amount of organic compounds in water. Most applications of COD determine the amount of organic pollutants found in surface water (e.g. lakes and rivers) or wastewater, making COD a useful measure of water quality. It is expressed in milligrams per liter (mg/L

Answer. There is a paper titled, The Science of Chemical Oxygen Demand, Lit 7053, which can found on the Hach website. This document provides detailed information on the reaction chemistry and methodology of COD. Additional information on alternative methods, including the COD2 and Manganese III COD methods, can be found in the files attached

Oct 16, 2009 · Chemical oxygen demand (COD) is a measure of the capacity of water to consume oxygen during the decomposition of organic matter and the oxidation of inorganic chemicals such as Ammonia and nitrite. COD measurements are commonly made on samples of waste watersor of natural waters contaminated by domestic or industrial wastes.

Chemical oxygen demand. In environmental chemistry, the chemical oxygen demand ( COD) is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution. It is commonly expressed in mass of oxygen consumed over volume of solution which in SI units is milligrams per litre ( mg / L ).

Hach TNTplus COD vial tests are available in multiple ranges. TNT823 provides a result in the Ultra High Range of 250 - 15,000 mg/L COD and is often used for Chemical Oxygen Demand measurement in industrial wastewater influent. Hach TNT823 does not require a separate blanking vial for further waste reduction.
