Description

The behaviors of N2O and NOx in the photo-reaction in N2O-NOx-N2 and N2O-NOx-air mixtures were studied. N2O was not changed by the presence of NO, NO2 and O3 and not affected by the UV irradiation with high pressure mercuy lamp. N2O decomposed to N2 and O2 under the UV irradiation with low pressure mercury lamp and the decomposition rate was proportional to the concet-ration of N2O. The reaction was not affected by NO, NO2 and O3. NO in N2O-NO-N2 mixture did not change under the UV irradiation with high pressure mercury lamp, while decomposed to N2 and O2 under the irradiation with low pressure mercury lamp and the decomposition was accelerated a little by O2 formed by the decomposition in N2O. NO in air was oxidized to NO2 under the dark reaction, while did not change under the irradiation with high pressure mercury lamp because of the formation of NO by the photo-decomposition of NO2. NO was photo-oxidized by the UV irradiation with low pressure mercury lamp. All of these reactions of N2O-NO-air mixtue were not at-fected by N2O. NO2 in N2 did not change in the dark reaction and decomposed to NO and O2 with high pressure mercury lamp irradiation. NO2 decomposed to NO and reduced partially to N2 by the low pressure mercury lamp irradiation. The rates of these reactions were same with those in the presence of N2O. NO2 in air decomposed to NO and O2 by the high pressure mercury lamp irradiation and was oxidized to higher oxides by the low pressure mercury lamp irradiation. These reaction rates were not change the presence of N2O,
