Influence de quelques facteurs sur la photodégradation catalytique de l'acide acétique en solution aqueuse par le TiO2
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.
