Abstract: The oxidation of sulfite is an important process in flue gas desulfurization by ammonia method. In this experiment, gas discharge was introduced to oxidize higher concentration of sodium sulfite under different voltages and frequencies. The results indicated that gas discharge could enhance the oxidation with rather low power consumption. By using power of DC superimposed AC, oxidation rate rose with increase of voltage but had nothing to do with frequencies in this experiment.

Key words: Sulfite, Gas discharge, Oxidation, DC superimposed AC, Non-thermal plasma
