| Abstract: | To investigate the influencing factors and the kinetics of photocatalytic degradation of phenol, experiments were carried
out using conjugated polymer poly(fluorene-co-thiophene) (PFT) sensitized TiO2 and ZnO under LED (light-emitting diode) lights of the wavelength of 450–475 nm. Influencing factors, such as initial phenol
concentration, photocatalyst dosage and pH value on the photocatalytic degradation of phenol were studied in detail. The reaction
kinetics was found to follow pseudo first-order law. |
