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. WebbThe amount of oxygen to require for oxidizing carbon atoms is CBOD, the amount required for oxidizing nitrogen atoms of organic material is NBOD, and CBOD+NBOD is considered theoretical oxygen demand (ThOD). Theoretically, we can use stoichiometry of the oxidation reaction of organic molecules to calculate the biochemical oxygen demands.

Theoretical oxygen demand (ThOD) is the calculated amount of oxygen required to oxidize a compound to its final oxidation products. However, there are some differences between standard methods that can influence the results obtained: for example, some calculations assume that nitrogen released from organic compounds is generated as ammonia, whereas others allow for ammonia oxidation to nitrate. Therefore, in expressing results, the calculation assumptions shoul…
