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, 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, N, and N. In particular, NO was detected during air discharge. The NO and could produce ; then generated nitric acid would affect the pH value of the solution. The intermediate product by N discharge is nitrophenol, and nitrophenol would be converted to -benzoquinone. The O discharge could produce an intermediate product of aminophenol. The intermediate products in Ar discharge were in small amounts and the final mineralization effect was the best.
本文研究了在不同放电气体氛围下，气态流光放电等离子体沿水面降解苯胺的效果及影响因素。对于初始浓度为100mg/L的苯胺，在反应器不通风时降解速度最快，处理7.5min时降解率为98.5%。而在通入氩气时降解最慢，处理60min后降解率为98.6%。放电过程中使用多通道光纤光谱仪检测到了一些活性粒子，如氩、羟基、氮和氮。特别是在空气放电过程中检测到了一氧化氮。一氧化氮和（此处原文可能有误，推测为某种物质）能产生（此处原文可能有误，推测为某种产物）；生成的硝酸会影响溶液的pH值。氮放电的中间产物是硝基苯酚，硝基苯酚会转化为对苯醌。氧放电会产生氨基酚中间产物。氩放电的中间产物较少，最终矿化效果最佳。
