摘要
In this paper, the degradation of aniline by plasma which was generated in a localizedzone between an electrolytic solution and an anode was reported. The influence of the initialconcentration, temperature, pH and different mediums of aniline on the reaction kinetic wasinvestigated. The results showed that temperature had a remarkable effect on the degradation ofediline, but the concentration had no appreciable effect on the degradation. There is a maximumelimination rate on the degradation of aniline in neutral condition. lron (Ⅱ) and other cationshad a remarkble catalytic action on it. On the basis of the detailed analysis of the kineticalconsideration, 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 byHPLC.
