摘要: Abstract A process capable of simultaneously oxidizing NO, SO2, and Hg0 was proposed, using a high-voltage short-duration positive pulsed corona discharge. By focusing on oxidation efficiencies, the influences pulse peak voltage, frequency, initial concentration, electrode number, residence time water vapor addition were investigated. The results indicate that SO2 efficiencies depend primarily radicals (OH, HO2, O) active species (O3,H2O2, etc.) produced by could be improved as number increased, but they reduced with increasing concentrations. adding vapor, efficiency remarkably, while NO decreased slightly. In our experiments, simultaneous reached to 40%, 98%, 55% concentrations 479 mg/m3, 1040 15.0 μg/m3, respectively.
