Universidad de Zaragoza (orcid)0000-0002-1401-7511 Photoactivation and photoregeneration of TiO2/PAC mixture applied in suspension in water treatments: approach to a real application 2021 Access copy available to the general public Unrestricted The process TiO2/PAC/UV-vis has been under study and compared with the isolated treatments of adsorption and photocatalysis determining possible synergies between adsorption and photocatalysis of target antibiotics: amoxicillin, enrofloxacin, sulfadiazine, and trimethoprim. The characterization of the TiO2/PAC mixture was carried out via FESEM and FTIR. Moreover, a kinetic study has been performed. The effect of UV-vis radiation and the type of matrix was analyzed in TiO2/PAC/UV-vis process. The performance of this treatment has been monitored during three cycles, evaluating also the regeneration of TiO2/PAC mixture by UV-vis light. TiO2/PAC/UV-vis process allowed the removal of the antibiotics in the range 90–100% (an average removal of 93% of the initial concentration) after 60 min of treatment. However, only amoxicillin showed a significant synergy applying TiO2/PAC/UV-vis process. Regarding matrix effect, no influence of the matrix type (ultrapure water or treated wastewater) was observed. Since PAC tends to be deactivated gradually, the TiO2/PAC/UV-vis process performance decreases after each cycle in a 15% average. Finally, regeneration via UV-vis light started to be effective after a total of 4 h of regeneration. info:eu-repo/grantAgreement/ES/DGA-FEDER/B43-20R info:eu-repo/grantAgreement/EUR/INTERREG-POCTEFA/OUTBIOTICS-EFA183/16 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 5.19 2021 ENVIRONMENTAL SCIENCES 87 / 279 = 0.312 2021 Q2 T1 0.831 2021 Environmental Chemistry 2021 Q1 Pollution 2021 Q1 Health, Toxicology and Mutagenesis 2021 Q1 6.6 2021 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Berges, J.
