Abstract

Destruction of isotopically labeled nitric oxide (15N18O) in air by corona discharge was studied using tubular-flow, coaxial wire, AC-powered dielectric barrier corona discharge reactor coupled with on-line quadrupole mass spectrometer. The kinetics and products of the destruction were determined as functions of specific discharge energy. There has been no direct confirmation of molecular nitrogen production in the process of NO destruction in air by corona discharge due to the overwhelming excess of these molecules in the bath gas. Use of 15N and 18O labeled NO allowed to overcome this difficulty. Reduction of NO to molecular nitrogen was clearly demonstrated. The concentration profiles of all nitrogen oxides were measured and compared with model calculations.
