| 摘 要： | In this paper,the degradation of aniline by plasma which was generated in a localized zone between an electrolytic solution and an anode was reported.The influence of the initial concentration.temperature,pH and different mediums of aniline on the reaction kinetic was investigated.The results showed that temperature had a remarkable effect on the degradation of aniline,but the concentration had no appreciable effect on the degradation.There is a maximum elimination rate on the degradation of aniline in neutral condition .Iron(II) and other cations had a remarkble catalytic action on it .On the basis of the detailed analysis of the kinetical consideration,it was demonstrated that the oxidative degradation would be a first-order reactioin,Some of the intermediate products of the degradatio process in the solution were detected by HPLC.

| Abstract: | In this paper, the degradation of aniline by plasma which was generated in a localized zone between an electrolytic solution and an anode was reported. The influence of the initial concentration, temperature, pH and different mediums of aniline on the reaction kinetic was investigated. The results showed that temperature had a remarkable effect on the degradation of aniline, but the concentration had no appreciable effect on the degradation. There is a maximum elimination rate on the degradation of aniline in neutral condition. Iron (Ⅱ) and other cations had a remarkble catalytic action on it. On the basis of the detailed analysis of the kinetical consideration, it was demonstrated that the oxidative degradation would be a first-order reaction.Some of the intermediate products of the degradatio process in the solution were detected by HPLC. |
