摘要：
The combination of dielectric barrier discharge plasma (DBD) and ultraviolet irradiation (UV) on the decomposition of toluene was studied. The decomposition rate of toluene by combination of DBD and UV, as well as reaction products were studied in a 0.5 m(3) stainless steel closed chamber. The synergetic effect was found in toluene decomposition by combination of DBD and UV. This parameter increases sharply in comparison to the decomposition rate of toluene by both DBD and UV separately. Ion cluster concentration was also increased whereas ozone accumulation concentration was dramatically decreased. An obtained phenomenon was discussed due to the difference of oxidation rates between ozone and hydroxyl radicals which are produced by the decomposition of ozone by UV light.
