Originální abstrakt

The reaction kinetics in argon – oxygen flowing afterglow (post-discharge) was studied using NO titration and optical emission spectroscopy. The O(3P) atom concentration was determined by NO titration at different places along the flow tube. The optical emission spectra were also measured along the flow tube. A zero-dimensional kinetic model for the reactions in the afterglow was developed. This model allows to calculate the time dependencies of particle concentrations. The wall recombination probability for O(3P) atoms γO = (1.60 ± 0.01) ×10-3 and wall deactivation probability for O2(b 1Σg+) molecules γO2(b) = (1.56 ± 0.03) ×10-3 were determined from the fit of model results to experimental data.
