Wüstite was characterized, showing 2.1 eV of bandgap and species of Fe3+ on the surface that favor its catalytic ability. The effect of light intensity, wüstite dose, concentration of H2O2, and pH on the removal of antimicrobial activity (AA, against S. aureus and E. coli), was tested, finding as suitable conditions: intensity]: 500 W m-2, wüstite]: 10 mg L-1, H2O2]: 1.0 mmol L-1, and pH 6.5. Under such conditions, up to 100% of AA elimination occurred at 180 min of treatment. The Light-Wüstite-H2O2 system involved, the action of light, O2•-, 1O2, and HO•, where wüstite acted as a semiconductor and a catalyst for heterogeneous photo-Fenton. Furthermore, this system mineralized 21% of ENR, and the wüstite catalyst promoted 100% of AA removal up to the fourth reuse cycle. Interestingly, the application of Light-Wüstite-H2O2 to an actual effluent led to complete AA removal after 180 min treatment. The process action on ENR generated six stable products, exhibiting the loss of the fluorine atom (induced by light directly) and modifications on the ethyl-piperazyl group (reactive region according to calculations of atomic charge) by radical attacks. The relationship between the AA and structural transformations showed that those products that retained quinolone and piperazyl moieties had AA. © 2022 Elsevier B.V. 000165132 536__ $$9info:eu-repo/grantAgreement/ES/DGA-FEDER/B43-20R$$9info:eu-repo/grantAgreement/ES/MCINN/MAT2017-83468-R 000165132 540__ $$9info:eu-repo/semantics/closedAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000165132 590__ $$a15.1$$b2022 000165132 591__ $$aENGINEERING, ENVIRONMENTAL$$b3 / 55 = 0.055$$c2022$$dQ1$$eT1 000165132 591__ $$aENGINEERING, CHEMICAL$$b5 / 141 = 0.035$$c2022$$dQ1$$eT1 000165132 592__ $$a2.803$$b2022 000165132 593__ $$aChemical Engineering (miscellaneous)$$c2022$$dQ1 000165132 593__ $$aIndustrial and Manufacturing Engineering$$c2022$$dQ1 000165132 593__ $$aEnvironmental Chemistry$$c2022$$dQ1 000165132 593__ $$aChemistry (miscellaneous)$$c2022$$dQ1 000165132 594__ $$a21.5$$b2022 000165132 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000165132 700__ $$0(orcid)0000-0002-0901-8341$$aHerrero-Albillos, J.$$uUniversidad de Zaragoza 000165132 700__ $$0(orcid)0000-0003-3014-0322$$aOrmad, M.
