T his work presents a chemical kinetic analysis of different species involved in nitrogen oxygen mixed gas by a Corona Discharge ( at room temperature and atmospheric pressure. This study takes into account 20 di fferent chemical species reacting following 1 5 0 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 work s have study removal NO x and they have showing the role of N, O and O 3 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 tempor al depopulation rate evolution (10 9 10 3 s) of NO x . We have found that the rate depopulation of NO and NO 2 is substantially affected by the reduced electric field rise from the initial value of 100 Td up to 200 Td. Thus, we have obtained in our sim ulation 2% of NO removal fo r 100 Td against 96% for 200 T d . This allows us the important role played by the reduced electric field.
