Photo-Fenton and modified photo-Fenton at neutral pH for the treatment of emerging contaminants in wastewater treatment plant effluents: A comparison

► This study compares photo-Fenton at pH3 and modified photo-Fenton at neutral pH. ► This study evaluates contaminants in sewage Treatment Plants effluents. ► Experiments performed in a solar pilot plant and monitored by HPLC-QTrap-MS/MS. ► It was demonstrated in all cases the removal of over 95% of the contaminants. ► Photo-Fenton modified with EDDS was promising as pH remained neutral.
