Abstract:
Degradation of aqueous 3, 4-dichloroaniline (3, 4-DCA) by wire-cylinder dielectric barrier discharge reactor was carried out in the present paper. Generation of reactive species was analyzed, changes of aqueous ozone concentration and solution pH values were examined; meanwhile, the effect of input power and initial pH value on the degradation efficiency of 3, 4-DCA were investigated. The results showed that the degradation efficiency of 3, 4-DCA increased with increasing input power when the input power was increased from 70 W to 90 W, while it decreased with increasing input power when the input power was increased from 90 W to 110 W; and the same changing trend was observed in the change of aqueous ozone concentration. At alkaline conditions and acidic conditions, 3, 4-DCA degradation rate was significantly higher than that of neutrality conditions. In addition, there was a remarkable decline of the solution pH values during 3, 4-DCA degradation.
