| Abstract: | The kinetics of photocatalytic degradation of methylene blue by titanium dioxide prepared via sol-gel method was investigated under UV irradiation. The experimental results indicate that the reaction of photocatalytic degradation of methylene blue is the first order kinetic model and the reaction rate constant is 1.67 10~(-2)min~(-1). The degradation rate increases with increasing of light intensity. To obtain the highest reaction rate, the amount of catalyst is 1.2g/L. |
