Abstract

This paper investigated the catalytic ozonation of aqueous nitrobenzene (NB) in the presence of nano-TiO₂/zeolite. The removal efficiency of NB was increased from ozone alone at 12.57% to in the present of catalyst at 33.76%, significantly. The optimum calcination temperature of nano-TiO ₂/zeolite was found out at 600°C. Catalytic ozonation of nitrobenzene was first order reaction with respect to the initial concentration of nitrobenzene. With the dose of radical scavengers increased, the degradation of NB decreased significantly, which proved that OH· was the dominating species in the oxidation process. Removal rate of NB increased with the increase of temperature from 10°C to 40°C. NB degradation varied with pH value, and reached the best removal rate at approximately pH 10. Catalyst showed good stability after 3 times repeated uses.
