WebbCompute the theoretical oxygen demand (ThOD) by 30 mg/L of bacterial cell, assuming the following reactions apply: C 5 H 7 NO 2 + 5O 2 barb2right 5CO 2 + 2H 2 O + NH 3 NH 3 + 2O 2 barb2right NO 3-+ H + + H 2 O (Solution) ... 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…
Relationship between chemical and theoretical oxygen demand …
Webb8 apr. 2024 · Not all of them are completely oxidizable, so the analyzed value can be either lower than the theoretical value or higher due to reactions between the oxidizing agent and certain ions of the substance to be analyzed [62,63,64,65]. An overview of the analyzed COD and theoretical oxygen demand (ThOD) of 582 substances is given by . the price is right it\u0027s optional

Webb 1. STEP 1 : Gather data for theoretical oxygen demand calculation 2. STEP 2 : Calculate the ThOD Webbtheoretical oxygen demand ThOD maximum theoretical amount of oxygen required to oxidize a chemical compound completely, calculated from the molecular formula Note 1 to entry: It is expressed as milligrams of oxygen uptake per milligram or gram of test compound. 3.5 theoretical amount of evolved carbon dioxide ThCO 2 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 sight lines architecture
