Decomposition of perfluorooctanoic acid photocatalyzed by titanium dioxide: Chemical modification of the catalyst surface induced by fluoride ions

- Photocatalytic treatment of PFOA solutions with TiO2 slurry.
- TOC analysis to evaluate the carbon content of the treated PFOA solution.
- IC analysis to evidence the photodegradation promoted production of fluoride ions.
- XPS and XRD analyses of TiO2 to monitor surface variations promoted by fluoride ions.
