Regeneration approaches for TiO2 immobilized photocatalyst used in the elimination of emerging contaminants in water

- Immobilized photocatalyst based on TiO2 on glass spheres was successfully applied for ECs removal.
- Regeneration with H2O2/UV or calcination are the most efficient methods to recover photoactivity.
- F-, S- and Cl-containing compounds are preferentially adsorbed and easily removed from titania acid sites.
- Compounds containing amine and amide groups are resistant to the photodegradation.
