Abstract

A laboratory experiment on methyl orange degradation in pulsed corona discharges was carried out. Effects of operating parameters such as applied voltage, pH, conductivity and initial concentration on methyl orange degradation were investigated. The pulsed corona discharges decreased the pH of solution and increased conductivity, probably due to products generated from methyl orange degradation by corona discharges. The decrease of initial pH enhanced the methyl orange degradation. The methyl orange degradation was fastest in $100{\mu}S/cm$ conductivity solution, followed by 50 and $200{\mu}S/cm$, indicating that $100{\mu}S/cm$ is the most favorable in the aspect of radical generation among the experimented conditions. The methyl orange of initial concentration from 20 to 60mg/L was effectively degraded in pulsed corona discharges. The lower initial concentration of methyl orange, the faster degradation was observed.
