摘要:

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 between 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.
