In predicting oxidants concentration, the most important fact is to select a suitable photochemical reaction mechanism. Sensitivity analysis of O3 and other important photochemical oxidants concentrations was conducted by using CBM-IV model.
The predicted oxidants concentration was considerably related with the initial concentration of formaldehyde, [NO2]/[NO],NOx, RH and RCHO. As the initial concentration of formaldehyde increased, concentration of NO2 increased. O3 concentration was proportional to the [NO2]/[NO] ratio. When the initial concentrations of RH and RCHO were high, photochemical reaction was more reactive, including more rapid conversion of NO to NO2 and increased oxidants. Also, the sensitivities of ozone formation to rate constants, Kl,K2andK3 in the NO2 photolysis were studied.
