“…The NO, SO 2 , and Hg 0 oxidation efficiencies reached to 40%, 98%, and 55% respectively [41] . NTP has been proposed to a potential method of oxidizing Hg 0 to Hg 2+ effectively as a co-benefit during the removal of NOx and SO 2 [35,[42][43][44] . Recently we have examined the oxidation of Hg 0 by PCD and DBD to know the effect of HCl on the oxidation of Hg 0 to HgCl 2 and to compare the Hg 0 removal efficiency between direct discharge and O 3 injection methods [35,[43][44] .…”

With the rapid development in industrialization and urbanization, various air pollutants are emitted into atmospheric environment. NO, SO2, Hg0are the most important pollutant in the flue gas. The application of non-thermal plasma (NTP) technology in the removal of NO, SO2, Hg0was reviewed respectively. Environmental applications have mainly involved plus corona discharge (PCD) and dielectric barrier discharge (DBD) system. In the future, the application of plasma technology in the flue gas could be focused on multiple pollutants synergistic mechanism.

“…As a kind of non-thermal plasma, atmospheric pressure plasma has been used in many fields, including sewage treatment [10], electrostatic dust collection [11], fog collecting [12,13], artificial precipitation [14,15], plasma medicine [16], device cooling [17,18]. Atmospheric pressure plasma is rich with active particles, especially the high energy electrons, which is enough to produce excitation, ionization and dissociation of various molecules.…”

Considerable research efforts have been devoted to the study of the application of atmospheric discharge in soil remediation. Most of them focused on how to improve the degradation efficiency of specific pollutants. In contrast, the generation and development of discharge in soil is less studied, which restricts the widespread application of soil remediation. Pulse voltage is widely used to trigger discharge in soil, but the requirement for the power supply is relatively high. The current paper proposes a new form of discharge voltage, with positive pulse voltage superimposed on DC bias. The results show that the existence of DC component can effectively lower the required pulse voltage and enlarge the active corona volume, in which area most ionization and excitation happens. The characteristics of corona discharge in soil under DC voltage only, pulse voltage only and superimposed voltage with various voltage components are discussed in detail, according to the volt-ampere characteristics and discharge images from a series of experiments. The mechanism behind the experimental phenomenon are also discussed.
