Effect of Carbon Monoxide on Photochemical Reaction (II)

Abstract

In our first report, the effect of carbon monoxide on nitric oxide oxidation, ozone formation and hydrocarbon consumption was discussed by a photochemical model. The authors have revealed in the same method the influence of carbon monoxide on photochemical products in this paper. In the presence of HC, it is estimated that the formation of HCHO, RCHO, H₂O₂, CO₂, NO₃ and N₂O₅ is accelerated by CO. On the other hand PAN level is decreased. The effect of CO on HNO₂ and HNO₃ is not distinguished. Furthermore, in the absence of HC, the effect of carbon monoxide become clear on photochemical products of NO-NO₂-CO-Air system. This estimation shows good agreement with the result obtained by K.L. Demerjian et al.
