ملخص

The influence of atmospheric corona discharge on the photocatalytic oxidation of acetone (83 ppm), acetaldehyde (108 ppm), and toluene (12-46 ppm) vapors on TiO2 under the action of soft UV light in a closed chamber has been studied. Corona discharge was created around the wire of the charging unit of an electric filter at the inlet of a photocatalytic reactor. The rate of the removal and deep oxidation of substances to CO2 increased considerably and reached maximum for acetaldehyde. The concentrations of inter-mediates in the course of experiments did not exceed 1 ppm. In the presence of corona discharge, the rate of deep oxidation per unit of consumed electric power increased by a factor of 1.2-3.6. The results show that combined photocatalytic and plasmochemical oxidation is promising for the purification of released gases.
