Theoretical oxygen demand thod
WebbTheoretical oxygen demand (ThOD) is the stoichiometric amount of oxygen required to oxidize a compound to end products such as CO2, NH3, H2PO42, SO422, and H2O. CODCr can be estimated from ThOD using the following equation:7 CODCr = a3 ThOD, (1) where a is an empirical constant. The ThOD for each of the chemicals in this study was WebbII) ThOD: Example 1.2:- Calculate the Theoretical Oxygen Demand (ThOD) for sugar C12 H22 O11 dissolved in water to a concentration of 100 mg/L.
