Treatment of Chloroform and Chlorobenzene vapors by novel methods

In the last 20 years, biologic process, photocatalysis process and plasma technology have been considered as methods for removal of volatile organic compounds (VOCs) and chlorinated volatile organic compounds (CVOCs). Non-thermal (non-equilibrium) plasma (NTP) has been more taken into account for VOCs degradation because it creates a very strong radical and oxidant agents that degrade VOC molecules in ambient pressure and temperature. Application of the NTP technique is limited due to the formation of harmful byproducts such as carbon monoxide, ozone and NOx. In recent years, many researchers have investigated the combination of NTP with PCO and reported that this system has a synergistic effect. The objective of this study was to investigate the effect of the combined system of PCO with NTP on the removal of chloroform and chlorobenzene vapors.
