In this study, an apparent reaction kinetic model is established for high‐gravity intensified Fe‐MnOX/AC‐catalyzed ozonation of phenol in a rotating packed bed (PRB). It is found that this model can accurately predict the removal rate of phenol, with the deviations between experimental and theoretical values being less than 8%. The rate constants of the direct reaction of ozone and the indirect reaction of ·OH and the parameter RCT are obtained, based on which their contributions to the removal of phenol can be more accurately estimated. The contribution factor is 77.5% for the direct reaction (fO3) and 22.5% for the indirect reaction (f•OH), respectively. This study provides a feasible method to establish the kinetic model for heterogeneous catalytic ozonation of organic matter, as well as new insights into the direct and indirect reaction mechanism of ozone with phenol.
