Effect of inorganic ions on the photocatalytic treatment of agro-industrial wastewaters containing imazalil

- The photocatalytic elimination of imazalil was proved for different water matrices.
- Commercial Evonik P25 and a home-made photocatalyst were studied and compared.
- The effect of different cations and anions was evaluated at different pH values.
- FTIR studies confirmed the interaction of ions with the photocatalyst surface.
- The degradation pathway of imazalil was confirmed for the different water matrices.
