This work presents a chemical kinetic analysis of different species involved in nitrogen-oxygen mixed gas by a DC (Corona Discharge) at room temperature and atmospheric pressure. This study takes into account 20 different chemical species reacting following 150 selected chemicals reactions. The reaction rate coefficients are taken from the literature and the density is analyzed by the continuity equation without the diffusion term. Many works have study removal NOx and they have showing the role of N, O and O3 radicals. So the aim of this simulation is to complete these studies by analyse of various plasma species under different reduced electric field: 100-200 Td. We analyse especially, the temporal depopulation rate evolution (10-9 – 10-3 s) of NOx. We have found that the rate depopulation of NO and NO2 is substantially affected by the reduced electric field rise from the initial value of 100Td up to 200Td. Thus, we have obtained in our simulation 2% of NO removal for 100Td against 96% for 200Td. This allows us the important role played by the reduced electric field.
