(Photo)-Fenton vs. direct photolysis of enrofloxacin: novel degradation kinetic study employing fluorescence spectroscopy with the multy-way method parafac

Fluoroquinolones (FQs) are broad-spectrum antibiotics extensively used in veterinary and human medicine. In terms of popularity, FQs are the third largest group of antibiotics accounting for 17% of the global market share (Hamad, 2010), so being highly consumed worldwide. On the other hand, these antibiotics are excreted unmetabolized up to 70%, as well as their metabolites could be just another FQ, as it is the case of enrofloxacin, which is excreted as ciprofloxacin (Van Doorslaer, Dewulf, Van Langenhove and Demeestere, 2014).
