Application of surface wave plasmas as an alternative technology for the destruction and removal of chlorinated hydrocarbon pollutants is demonstrated. The destruction of parts per thousand concentrations of trichloroethylene in air/water or oxygen mixtures has been investigated in a low-pressure reactor at 5 Torr. Effluent analysis included the determination of destruction and removal efficiencies by electron capture gas chromatography and product distribution by Fourier transform infrared spectroscopy, mass spectrometry, and titrimetric analysis. TCE conversions of up to 99.998% were achieved using radio frequency power densities ranging from 1.6 to 7.5 kJ/L and millisecond range residence times within the plasma. Product analysis indicated that trichloroethylene conversion was limited to light gases, primarily CO 2 , CO, HCl, and Cl 2 .

The effluent gas-phase composition from the atmospheric pressure reaction between tetraethylorthosilicate (TEOS) and ozone was investigated as a function of reactor temperature and initial reactant molar ratio. Online, continuous quantitative determination of gas species was achieved using Fourier transform infrared techniques. TEOS decomposition was a function of initial ozone concentration and reactor temperature. Ozone enhanced TEOS decomposition was found to generate carbon monoxide, carbon dioxide, formic and acetic acids, and water, in addition to unreacted source species.
