摘要
The photocatalytic degradation of acetic acid in an aqueous suspension of TiO2 has been studied. The influence of [TiO2], [CH3COOH] and irradiation time on the rate of disappearance of acetic acid has been demonstrated. We have brought to the fore that the disappearance of acetic acid follows the Langmuir-Hinshelwood model. Finally we have observed the effect of granulometry and the crystalline structure of the catalyst that shows that the degradation is made at the TiO2 surface.
