| Sumario: | 17β-estradiol (E2), ampicillin (AMP), as well as the synthetic dyes Red 40 and Yellow 5, have been included in the group of emerging contaminants (ECs). These generate different environmental problems such as endocrine disruption in aquatic biota at trace concentrations. Due to their complex structure, they are difficult to degrade by conventional treatments. Fenton-type advanced oxidation processes (AOP) have shown promising results in the oxidation of organic compounds in short reaction times. In this work, a photo-Fenton process was evaluated with sunlight for the elimination of E2, AMP, Red 40 and Yellow 5 dyes in water with H2O2 as an oxidizing agent and FeSO4·7H2O as a catalyst. Oxidation efficiencies of E2, AMP, Red 40 and Yellow 5 greater than 70% were obtained and the degradation followed a first-order reaction model. Therefore, photo-Fenton oxidation processes are efficient in the oxidation of E2 and AMP, as well as the decolorization of red 40 and yellow 5. |
