ABSTRACT
Chemical reaction kinetics of NO removal by pulse corona discharge under the condition of normal atmospheric pressure was studied by using dispersive fluorescence spectrum and time-resomved spectrum. The fluorescence spectrum of NO pulse corona discharge was obtained. Moreover, dactylograms of NO, and those of the N+, O, N2, produced in the process of discharging were confirmed by attributing the fluorescence spectrum, and then the time behaviors of these particles were studied by analyzing these dactylograms. The results show that, the NO molecule turns to NO+ ion after colliding with high-energy electron, and then the NO+ ion breaks down to N+ and O. Subsequently, the N+ ion turns to N atom after absorbing an electron and then combines with another N atom, while the O atom turns to O2 molecule when combining with another O. From these results, the chemical kinetics model of NO removal by pulse corona discharge was proposed, which is helpful to increasing NO removal rate.
