Abstract
The presented work has applied model water solutions saturated with Benzene, Toluene, Xylene and their mixtures. They have been subdued to an ozonization process in static and dynamic conditions. Nonequilibrium plasma has been obtained in a tubular ozonizer made of stainless steel equipped with a glass dielectric. Discharges have been generated by sinusoid current of (3.5kV, 4kV, 5kV 5.9kV voltage at carrier gas flow rate of 50 dcm3/h). Dissolved oxidizing mixture (03+02) has been applied to benzene and toluene water solutions under static conditions for 20 min. Benzene and Toluene water solutions have also been exposed to hydrogen dioxide under the same conditions. The compound content in the solutions has been subdued to extraction in methylene dichloride prior to the plasma application and after the process completion. Quality and quantity analyses have been performed by means of gas chromatography with the application of flame-Ionization detection. In static conditions a decomposition rate reaching 97% has been obtained for Benzene and Toluene. The biggest drop of the hydrocarbon content has been observed in the case of Xylene and the smallest one - in the case of Benzene. Obtained results have been summarized and compared by means of a Chromax 2003 and presented in a graphical form.
