ABSTRACT

The repercussions of introducting chlorinated and fluorinated molecules into natural wet air plasmas are analysed. The study deals with the multiple aspects of plasma composition and of modification of the intensity and shape of the spectra emitted by the main chemical species. Some rapid methods, largely insensitive to halogenic compounds and water concentrations were propounded for temperature determination. The effects of radiative and thermal non-equilibrium were considered.
