Background of development
In environmental chemistry, 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) also referred
to as ppm (parts per million), which indicates the mass of oxygen consumed per liter of solution.
