Effective inhibition of antibiotic residues and bacterial pathogens in wastewater using TiO2 metal oxide photocatalyst.
Antibiotic residues have become serious health concerns due to the development of antibiotic-resistant bacteria. The treatment of antibiotic pollutants in wastewater is necessary for reducing the issue of antibiotic resistance. In this work, the metal oxide photocatalyst titanium dioxide (TiO2) was evaluated for the removal of the tetracycline antibiotic (TC-A) and the deactivation of E. coli bacteria (E-B) from wastewater. Based on the oxidation process, TiO2 can successfully degrade TC-A in wastewater with an efficiency of up to 96.4%. It is also employed for the deactivation of E. coli, completely inactivating the bacteria within 30 min. Moreover, after five cycles of reuse, TiO2 demonstrated high removal efficiencies of over 80% and 95% for TC-A and E-B, respectively. Finally, the proposed mechanism for the removal of TC-A and the deactivation of E. coli using the TiO2 photocatalyst is presented. This work provides a simple method for removing antibiotic pollutants and deactivating bacteria in wastewater.
