Abstract :
Photocatalytic oxidative kinetics of thiophene in n-octane/water extraction system was studied with nano-TiO2 powders as photocatalyst and O2 in air as oxidant. Influence of initial concentration of thiophene and addition of TiO2 on reaction rate constant and half time were investigated. Kinetics equation was founded. The results showed that the approviate addition of TiO2 was 0.1 g in 100 mL reaction system and the photooxidation kinetics of thiophene with TiO2 was first-order with rate constant of 0.6405 h-1 and half-time of 1.0822 h under the conditions with initial concentration of thiophene at 800 muLldrL-1 and addition of TiO2 at 0.1 g. The reaction rate constant increased with the decrease of initial concentration of thiophene.
