The preliminary discharging characterization of a novel APGD plume and its application in organic contaminant degradation

Year: 2006

Type: article

Abstract: An atmospheric pressure glow discharge plume (APGD-p) using a dielectric barrier discharge reactor with one conductive liquid electrode was designed in our study. The preliminary characteristics of the plume and application in the degradation of a dye, methyl violet 5BN (MV-5BN), were presented in this paper. The APGD reactor produced a cold plasma plume with temperature not higher than 320 K at power 5–50 W. The MV-5BN solution as a probe for dye wastewater was treated by the downstream gases of the plasma plume. The results indicated that the active argon (Ar) and nitrogen (N 2 ) gases had little effect on the MV-5BN degradation, but the air and oxygen (O 2 ) gas depleted the organic molecules effectively. In particular, the downstream O 2 gas degraded the dye molecules entirely.
