Abstract

A novel catalyst for the ozonation process was prepared by loading manganese on the granular activated carbon (GAC). Nitrobenzene was used as a model refractory organic micropollutant in this study. The catalytic activity of GAC and the Mn-loaded GAC were studied respectively. The removal efficiency of nitrobenzene by Mn-loaded GAC catalyzed ozonation could reach 34.2-49.9%, with the oxidation efficiency being about 1.5-2.0 times higher than that achieved in GAC catalyzed ozonation and 2.0-3.0 times higher than that achieved by ozonation alone. The effect of pH and the t-butanol on the GAC/ ozone process was discussed. The optimum condition for preparing the catalyst was studied.
