Theoretical oxygen demand thod
WebbThe oxidation behavior of twenty organic chemicals from four different classes (sugars, benzene derivatives, alcohols and carboxyl acids) were investigated using the official chemical oxygen demand (COD) methods ( i.e., permanganate and dichromate methods) and their oxidation levels compared with the theoretical oxygen demand (ThOD) values. WebbOxygen Demand is a measure of the amount of “reduced” organic and inorganic matter in a water. It relates to oxygen consumption in a river or lake as a result of a pollution …
