Abstract:	OH radicals play an essential role in various plasma-chemical processes aimed at the abatement of organic and inorganic pollutants from off-air flows. We report about the oxidation of carbon monoxide in nonthermal air and nitrogen plasmas in dependence on CO inlet concentration and flow humidity. Thereby the reaction CO + OH CO₂ + H served as a diagnostic tool for OH radical determination in the dielectric barrier discharge at atmospheric pressure. The results were numerically fitted to the equations of a kinetic model allowing the determination of the average OH production efficiency (G_OH-value) and OH lifetime (T_OH) in dependence on flow humidity. Finally,results on ethyl acetate abatement obtained under similar experimental conditions were modeled by OH radical decomposition.
