Development of an Empirical Rate Law using Initial Rate for the Degradation of Diisopropanolamine using Photo-Fenton

Alkanolamines such as diisopropanolamine are used to treat natural gas so as to remove the acid gases, carbon dioxide etc in it. The wastewater of this process will content high amount of the amines in which causes high COD reading in it. Therefore, methods of degrading the recalcitrant pollutant were introduced, in which photo-Fenton is added into the wastewater and undergo oxidation process producing •OH radical which later will react with the amines and degrade them.
Focusing on the effect of concentration of both reagents and amines, empirical rate law is developed to obtain the optimum condition parameter for the degradation of diisopropanolamine in natural gas processing plant wastewater using photo-Fenton.
The proportionality constant, k, or the rate constant is 0.779. It is safe to say that this reaction is (141/1000)th order in H2O2 and (1561/1000)th order in DIPA. The overall order of this reaction is (1442/1000) order which is the sum of all the orders of the reactants. This indicates a fractional order reaction, in which indicates the complexity of the reaction mechanism
