In this study, CoMnAl mixed metal oxides (CoMnAl-MMO) were prepared and employed in heterogeneous activation of Oxone for bisphenol A (BPA) degradation. Typically, 10 mg L-1 of BPA could be completely degraded under the coexistence of 0.02 g L-1 of CoMnAl-MMO and 0.15 g L-1 of Oxone within 90 min at 25 degrees C. The degradation performance was evaluated in view of metal leaching and various effects, e.g., pH, Oxone dosage and temperature. The results indicated that the system of MMO/Oxone was suitable for the treatment of wastewater and presented favorable recycling and stability in both neutral and alkaline conditions. It was confirmed that BPA degradation catalyzed by CoMnAl-MMO followed Well with the first order kinetics model and the an activation energy was calculated as 76.83 kJ mol(-1). The sulfate radicals were recognized as the main species to oxidize pollutants in the MMO/Oxone system. Particular attention was paid to the catalysis activation mechanism of peroxymonosulfate and the degradation pathway of BPA, which were analyzed by X-ray diffraction (XRD) and X-ray photoelectron spectroscopic (XPS), LC-MS and GC-MS.
