Abstract:

A new catalyst CeAC was prepared by impregnating activated carbon (AC) into the solution of cerium nitrate. CeAC catalyst was characterized by XRF. During the CeAC  heterogeneous catalyzed ozonation, the different removal effcts of pyrene and fluoranthene in different treatment processes and a series of different conditions  were compared. The biotoxicity of the treated water was detected. The mechanism of the reaction was also discussed.

Key words: ozone, heterogeneous catalytic ozonation, pyrene, fluoranthene, new kind of catalyst CeAC
