This work was indeed on the studies of gliding arc plasma discharge with respect to its use in decomposition of volatile organic compounds and on the solid phase microextraction analysis of the discharge products. The simple one stage gliding arc reactor was used for these experiments. The applied voltage generating the discharge was varied in the range of 3.5 - 4 kV, the dry air and its mixtures with nitrogen, oxygen and argon were used as carrier gas, with flow rate of 1000 - 1600 ml/min. The toluene was used as a model VOC and its maximal decomposition of 73 % was achieved at the oxygen content in carrier gas of 60 %. For measurements with air as a carrier gas, the maximum removal efficiency was 68 %. The exhaust gas was sampled during these experiments by solid phase extraction technique (sorption tubes) and analyzed by gas chromatography linked to the mass spectrometry. The other part of study was focused on the applicability study of solid phase microextraction technique for the gliding arc discharge products sampling. The discharge exhaust gas was sampled by three different kinds of SPME fibers and the product's analysis was done by GC-MS. The experimental results obtained by the destruction of cyclohexane and toluene as the model VOC compounds showed that this sampling technique can be used for the simple and cheep qualitative analysis of the discharge products. The results showed that the fiber coated by Carbowax/divinylbenzene (CW/DVB) can extract the highest number of destruction products independently on the used VOC representing compound. The Carboxen/polydimethylsiloxane/divinylbenzene (CAR/PDMS/DVB) fiber is useful for the oxygen containing compounds and its use will be recommended especially when the destruction is done in the air enriched by oxygen. The applicability of the polydimethylsiloxane (PDMS) fiber is strongly limitted.
