Ozone formation from a propene-nitrogen oxide-wet air mixture was modeled and simulated by using a detailed reaction model to characterize ozone formation in air pollution. Effects of reaction parameters such as light intensity, initial concentrations of propene and nitrogen oxides, temperature and humidity were investigated. The loss reactions of N₂O₅ by H₂O were incorporated in the model developed in the present study. Results of simulations showed good agreement with smog-chamber experimental data. From the results of simulations it was found that the maximum ozone concentration was little affected by humidity. The model proposed in the present study can be predict the amount of ozone formation successfully.
