Effects of light intensity and H2O2 on photocatalytic degradation of phenol in wastewater using TiO2/ACF
Titanium dioxide (TiO2) film was prepared on activated carbon fibre (ACF) by hydrolysis technique, using sulphate titanium as raw material. Based on the techniques of photocatalytic degradation using TiO2/ACF, and 254nm UV-ray as the light sources, aqueous phenol solution of 40mg/L was photocatalytic decomposed over TiO2 film. The result showed that TiO2/ACF exhibited a degradation efficiency of 88.2％ for phenol after 4h, while the condition of pH=7.5, the concentration of phenol is 40mg/L, power of ultraviolet light is 1.75W/L, and air quantity is 2.6mL/ (min-L). Analysis of photodegradation shows that the kinetics for photocatalytic degradation of phenol follwed pseudo-first-order kinetic law, and the initial concentration of phenol, pH value, light intensity, air quantity and H2O2 concentration affected the photocatalytic degradation rates.
