Abstract

Abstract: This work investigated the degradation of aniline in aqueous solution by PMS activated with CuFe2 O4 /activated carbon heterogeneous catalyst. Firstly, catalyst which was successfully synthesized by impregnation and calcination process was fully characterized. Next, influences of factors in degradation on this system were explored. Under optimum process conditions, system could achieve TOC removal rate of 87 % in 2 hours. Then the stability of the catalyst was proved. In addition, the synergistic effect between CuFe2 O4 and activated carbon was proposed in PMS activation at both low and high concentrations. Furthermore, it was observed that CuFe2 O4 /activated carbon could also activate PMS at low concentration. Finally, S O 4 - was suggested as the main activated species in this system by characterization and analysis. It is concluded that CuFe2 O4 /activated carbon catalyst could be used as an effective catalyst to activate PMS for the degradation of aniline. Abstract : A CuFe2 O4 /activated carbon catalyst was successfully synthesized and was used for activating PMS to degrade aniline for the first time. It reveals outstanding catalytic activity and synergistic effect between activated carbon and CuFe2 O4 in aniline degradation at room temperature and pressure.
