摘要

Information on the by-product distribution in plasma decomposition of volatile organic compounds is an important prerequisite to the understanding of the chemistry of plasma decomposition process and to achieve complete oxidation at a minimum energy cost. This research focused on analysis of by-products of the decomposition of toluene and xylene stripped from wastewater using ferroelectric packed bed non thermal plasma reactor operated at 15.68, 14 and 12.32 kV and fixed discharge gap and flow rate of 25 mm and 2.36 L/min respectively. The by-products were qualitatively analyzed with Fourier transform infrared spectroscopy. CO, CO2, H2O and N2O were identified as the by- products. Also, CO formation decreased with increase in applied voltage.
