Degradation of aniline in water with gaseous streamer corona plasma.

ABSTRACT: This paper demonstrated the effects and influencing factors in degrading aniline by gaseous streamer corona plasma along water surface under different discharging gas atmospheres. For aniline with an initial concentration of 100 mg l^-1, the degradation was fastest when the reactor was not ventilated, and the degradation rate is 98.5% under 7.5 min treatment. While the degradation was slowest when Ar was ventilated, the degradation rate is 98.6% after treatment for 60 min. Some active particles were detected using a multi-channel fibre-optic spectrometer during the discharge, such as Ar, OH, N₂, N 2 + and N. In particular, NO was detected during air discharge. The NO and N 2 + could produce NO 3 - ; then generated nitric acid would affect the pH value of the solu
