文摘

The addition of natural products improved the solar photo-Fenton disinfection process. Bacterial inactivation in WW was achieved despite the presence of added organic matter. The performance of CA and TA is attributed to the photo-activity of the Fe-CA/TA complexes. AA induces a direct reduction of Fe3+ and enhances the Fenton reaction. Photo-activity and direct reduction were involved in the CfA-induced effects.
