“…According to the results above reported, three interesting tasks should be addressed in the next future for a better understanding of the process: a) investigate the nature of the interaction between Fe and the FQs to explain the good performance of photo-Fenton at mild pH, b) to combine EEM-PARAFAC with smart HPLC-MS analysis to correlate the components obtained in the mathematical model with a compound or group of compounds, c) to explore the real applicability of the methodology here developed with lower pollutant concentrations (e.g μg/L), using different aqueous matrices (role of salinity and dissolved organic matter) and scaling it up to higher volumes using real sunlight as irradiation source. As an extension from previous works [119,137], we have followed with EEM-PARAFAC the degradation of a mixture of 5 quinolone-antibiotics: OFL, CIP, ENR, OA and FLU, in different water matrices: MQ, SW and simulated wastewater (SWW). Solar-photo-Fenton at pilot plant scale was used as water treatment.…”
