PCDD/Fs have been become a serious issue because of their toxicological e ects and associated adverse health implications. In this
study, the gliding arc plasma was tested for treatment of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans
(PCDFs), which was synthesized from pentachlorophenol in atmospheric condition at 350℃ with or without the catalysis of CuCl2.
From the experiment, we found that the destruction e ciency of PCDD/F homologues after gliding was discharge ranged from 25%
to 79%. This result demonstrates that gliding arc plasma is an e ective technology to decompose PCDDs/Fs in flue gas. A plausible
degradation mechanism for PCDD/Fs by gliding arc was discussed. Finally, a multistage reactor structure of gliding arc was proposed
to upgrade removal e ciency for PCDD/Fs.
