Degradation of Aniline by MnⅡ-BAP System Based on Metal Superoxide Species of MnO2+-(HCO3-)n
In order to effectively deal with aniline pollutants which are widely present in groundwater,the MnⅡ-BAP system was used to oxidize aniline,and systematically explored the oxidation process,the effect factors,and the main active species of oxidation.In the process of aniline oxidation in MnⅡ-BAP system,the optimal conditions and oxidation mechanism of aniline oxidation were investigated by kinetic experiments and quenching experiments.The experimental results showed that the MnⅡ-BAP system can oxidize 99.5％of aniline within 10 min,with a reaction rate constant of 5.30×10-1 min-1.The synergy be-tween Mn2+ and HCO3- will caused the concentration of HCO3- and Mn2+ in the reaction system to have an important impact on kobs,the superoxide species MnO2+-(HCO3-)n was the main active species for aniline oxidation in the MnⅡ-BAP system.
