A zero-dimensional model is used for studying the behaviors of NOx in atmosphere plasmas with different ionization degrees. The temporal evolutions of NOx (including NO, NO+, NO2, NO2+, N2O, N2O+, NO3 and N2O5), N and O3, the main important reactants which influence the producing and the consuming of NOx, are obtained in different initial densities for afterglow plasmas. The results show that the removal rates of NO and NO2 are higher when ne0=109 cm-3, and the total nitrogen oxide density is lower, so it is suited for the removal of the pollution of NOx. Some important reactants such as N and O3 varying with the increase of ionization degree are also analyzed.
