【 摘 要 】

This study aimed to investigate the efficiency of glass fiber which has been coated by TiO2doping with SnO2 and nitrogen. TiO2 films were prepared by sol-gel method and coated onE–glass type of glass fibers by using dip-coating. Then the films were calcined attemperature of 600°C for 2 h. The photodegradation efficiency of harmful chemicalswhich are humic acid (C0=10 mg/L), fulvic acid (C0=10 mg/L), 2,4-dichlorophenol (C0=10mg/L) and glyphosate (C0=1x10–4 M) contamination in water were investigated using aphotocatalytic reactor containing N–doped SnO2/TiO2 composite films coated on glassfibers. It was found that at the flow rate of 250 mL/min the photo-reactor degradation ofhumic acid, fulvic acid, glyphosate and 2,4-dichlorophenol contamination in water were91.30, 95.50, 71.80 and 88.70 %, respectively. It is apparent that TiO2 compositephotocatalytic reactor shows advantages in degradation of some hazardous chemicalcompounds contamination in water.
