Abstract

Abstract

To solve the problem of environmental pollution caused by the difficult degradation of antibiotics, Ce-TiO₂/SiC foam was prepared, levofloxacin (Levofloxacin, LEV) was chosen as the target pollutant, and a photocatalytic ozonation coupling system (Ce-TiO₂/SiC + LED + O₃) was studied. The results show that the coupling system can effectively degrade LEV, the LEV removal was 99% and the chemical oxygen demand (COD) removal was as high as 85.9%. The coupling system showed a good synergistic effect, and its first-order reaction kinetic rate constant was greater than the sum of ozonation (O₃) and photocatalysis (Ce-TiO₂/SiC + LED). In addition, the stability experiment of Ce-TiO₂/SiC foam showed that the photocatalytic ozonation activity is basically unchanged after five reuses.
- photocatalytic ozonation,
