Abstract:

To prevent toxic substances from entering and spreading through the environment and to meet increasingly stringent regulations, more effective methods of destroying chemical pollutants are being examined. Advanced oxidation processes, historically used for the treatment of recalcitrant water pollutants via hydroxyl radicals OH, are now being applied to the treatment of gas-phase pollutants using non-thermal plasmas NTPs. In NTPs, chemical decomposition can also be initiated by radicals other than OH, some of which may even be reductive rather than oxidative. Non-thermal or non-equilibrium plasmas in gaseous media are characterized by combined energetic-electron e.g., 1-1- eV and low-temperature gas conditions. Free radicals, particularly oxygen-atom radicals, are effectively generated by NTPs and play a key role in the process of ozone generation.
