In the atmospheric chemistry, CO oxidation monitoring method has been used to measure OH radicals concentration. The application of CO oxidation monitoring method to the OH radicals measurements in a pulsed discharged plasma in argon and H2O mixture at 1 atm was studied. The influence of the loss reaction of OH radicals could be ignored when initial CO concentration was > 2000 ppm. However, when CO concentration exceeded 1%, the CO2 concentration began to decrease due to a decrease in the peak discharge current. Thus, the influence of loss reaction depended on the initial concentration of CO. Production of OH radicals increased when the H2O content increased under the same specific input energy (SIE). The production of OH radicals increased with the SIE value when the H2O content was kept constant. These results agreed with other measurement on spectroscopic analysis of OH formation in dielectric barrier discharges of Ar/O2/H2O.
