| In this paper, the Fenton reaction was applied to enhance the degradation of toluene combining with corona discharge technology. Innumerable mini-droplets were formed in the discharge zone by spraying of Fenton-type reagents of Mn2+, Co2+ and Fe2+ solutions as catalysts. Results shown that the introduction of those metallic ions could remarkably increase the average degradation rate of toluene in the corona zone with better dosage of 0.05 mol•L-1 and in the order of Mn2+ > Co2+ > Fe2+ at the applied voltage 23 kV. The electric-Fenton reaction was proved to occur in the mini-droplet, in which the H2O2 generated in the discharge was converted to the •OH radical that enhanced the toluene degradation rate with its strong oxidizing ability. Dissolution of intermediate products into the mini-droplet was another way to enhance the toluene degradation rate. |
