The F-S-Bi-TiO2/SiO2 and F-S-Zr-TiO2/SiO2 photocatalysts were prepared by sol-gel method to degradate organic pollutants in acrylonitrile industrial wastewater. The catalysts activity evaluation showed Chemical Oxygen Demand (COD) in the wastewater decreased from 88-150 mg.L-1 to 20-30 mg.L-1 after reaction for 4 h under simulant sunlight irradiation, and COD decreased from 88.36 mg.L-1 to 38 and 50 mg.L-1 after reaction for 6 h under natural sunlight with F-S-Bi-TiO2/SiO2 and F-SZr- TiO2/SiO2 catalysts, respectively, to reach country emission standard.
