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 WebbThe ThOD is the sum of the oxygen required for all three steps. We can calculate by following steps: Write balanced reaction for the carbonaceous oxygen demand. CH 2 …
WebbThe OECD 301F closed respirometer method determines the biodegradability of a material by measuring oxygen consumption during the biodegradation process in a period of 28 days in a closed bottle setup (with head space). The degradation percentage is calculated as the ratio of oxygen consumption to the theoretical oxygen demand (ThOD).
