Chemical Oxygen Demand (COD): COD is the amount of oxygen needed to completely oxidize organic and inorganic substances present in water. COD is always greater than BOD since COD includes both biodegradable and non-biodegradable substances, whereas

Chemical Oxygen Demand (COD) Test Kits. These easy-to-use test kits determine COD a measure of the oxidizable organic matter content in a wastewater sample. Run test by pipetting sample into prepared ampoule, cap the ampoule, and mix.

Stock solution 1. Weigh 250 mg of the chemical on an analytical balance and transfer it into a 25 ml volumetric flask. 2. Fill to the mark with dilution water and shake vigorously. 3. Transfer 1 ml of the 25 ml volumetric flask to tube A and rinse the toxicant pipet.

2005/10/14 · 1. Introduction. Biochemical oxygen demand (BOD) is one of the most widely used and important parameters in the measurement of biodegradable organic compounds and pollutants in water. The 5-day BOD test (BOD 5) adopted by the American Public Health Association has been the standard method since 1936 [1].
