Abstract

Removal of elemental mercury $(Hg^0)$ with the reactive species produced from dielectric barrier discharge (DBD) was studied. We investigated the effect of operating parameters such as the applied voltage, residence time, initial concentration and co-existence of other pollutants. The removal of $(Hg^0)$ was significantly promoted by an increase in the applied voltage of the DBD reactor system. It is important to note that at the same input power, the removal efficiency of $(Hg^0)$ was much higher than that of NO gas. These results imply that if the DBD system is used as a NOx treatment facility, it is capable of removing $(Hg^0)$ simultaneously with NOx.
