Application of standard mixtures for the estimation of characteristics of non-equilibrium plasma of atmospheric pressure pulsed discharges

Abstract

The non-equilibrium non-thermal plasma of atmospheric pressure (NNP), which is generated by electric discharges, is widely used in air-cleaning technologies. In this paper, it is proposed to use the method of standard mixtures to estimate the qualitative and quantitative parameters of the NNP. Pulsed corona discharge was used for the experiments. As testing mixtures, two groups of standard volatile organic compound mixtures with a certain qualitative and quantitative compositions were used. One of them contains a set of functional compounds used as solvents of wide application, and the other—a set of chlorine-containing compounds. Different components of the model mixture react with plasma components at different rates. Thus, by studying the concentration dependencies of such mixtures, one can obtain information about the qualitative and quantitative composition of the NNP generated by the chosen method and to determine the energy efficiency of the method.
