“…Other common examples on materials used for tetracyclines photocatalytic degradation under both UV and visible light include the application and modification of titania (TiO 2 ) semiconductors. In these studies, both high performance liquid chromatography (Wang et al, 2011;Cao et al, 2016) or UV-VIS spectrophotometer (Yu et al, 2014;Oseghe and Ofomaja, 2018a;Lyu et al, 2019;Ghoreishian et al, 2020) were used for the analysis of the water samples and for the evaluation of the degradation efficiency of the TCs over the investigated photocatalysts. Photocatalytic tetracycline degradation mediated by TiO 2 is expected to proceed via the formation of intermediates, which eventually completely degrade into CO 2 , H 2 O, and NH 4 + .…”

“…Further modification of Titania is urgently needed to achieve practical, visible light-induced photocatalytic applications. Many studies have been reported in the literature to enhance Titania properties through modification and/or combination with organic and/or inorganic counterparts (Wang et al, 2011;Pouretedal and Afshari, 2016;Zhang F. J. et al, 2017;Chen and Liu, 2017;Jin et al, 2017;Duan et al, 2018;He et al, 2018;Tang et al, 2018;Zheng et al, 2018;Liu M. et al, 2019;Farhadian et al, 2019;Galedari et al, 2019;Sun et al, 2019;Akel et al, 2020;Ghoreishian et al, 2020;Liu et al, 2020;Divakaran et al, 2021;Ghoreishian et al, 2021).

“…This hybrid method specifically enhances the catalyst photo-efficiency by broadening the photo-activated spectrum toward the visible range. The N-TiO 2 catalyst is most commonly used for tetracyclines degradation under visible light, along with other nonmetal-doped TiO 2 in mixed doping systems (Huo et al, 2016;Chen and Liu, 2017;Rimoldi et al, 2018;Ghoreishian et al, 2020). Rimoldi et al (Rimoldi et al, 2018) used the sol-gel method to prepare Sn-, Zn-, and N-doped TiO 2 for tetracycline degradation under simulated solar irradiation.…”

Sub-therapeutic levels of antibiotics (ABs) are given to animals and poultry to promote growth and reduce disease. In agricultural environments, ABs reach croplands via animal manure used as fertilizer and/or ABs-contaminated water used for irrigation. The continuous discharge of ABs into the ecosystem raises growing concerns on the ABs contamination of edible crops. Tetracyclines (TCs) are among the most widely used ABs around the world. In this review, we discuss the contamination of irrigation water with TCs, its impact on edible crops, and the potential risks of crop contamination with TCs on human health. We propose solar-mediated photocatalytic degradation using Titania (TiO2) photocatalyst as a promising method to remove TCs from irrigation water. The photocatalytic activity of TiO2 can be enhanced by chemical modification to expand its activity under visible light irradiation. Herein, we aim for providing literature-based guidance on developing a visible light–active TiO2-based system to degrade TCs and other ABs in water streams. We include a summary of recent advances on this topic based on three main modification methods of Titania: metal/non-metal/mixed doping, composite formation, and heterojunction construction. Among the investigated photocatalysts, Fe2O3-TiO2/Fe-zeolite and the N-doped TiO2/rGO immobilized composite catalysts were found to be very efficient in the degradation of TCs under visible light irradiation (i.e., 98% degradation within 60 min). Most immobilized TiO2 based composite systems exhibited improved performances and hence we highlight these as efficient, cost effective and ecofriendly photocatalysts for the degradation of TCs in irrigation water.

“…The extensive use and untreated emissions of TC have led to its widespread presence in the water-soil environment. There has been much research on the adsorption and degradation of TC by doped TiO 2 [18][19][20]. Nitrogen is a promising doping element due to its lower ionization energy and atomic size similar to oxygen, which can reduce the bandgap of TiO 2 [19] and improve visible spectrum absorption [21].…”

N-doped and N-F co-doped TiO2/bentonite composites were synthesized via the gel-sol method. The morphology, structure and surface charge of the composite before and after adsorption were used to determine the effect N/F doping ratio on TC removal. The results showed that, compared with undoped samples, the TC adsorption on N doped composites was reduced by 24.44% on average. N-F co-doping significantly increased the TC adsorption when the Ti-N-F molar ratio was 1:1: 0.01, reaching a maximum TC adsorption of 64.00 mmol·kg<sup>-1</sup>. The coverage of the N doped TiO2 increases as the N doping ratio increases; the specific surface area increased by 2.03 % on average, but the number of surface negative charges decreased by 36.24 % on average. FT-IR results confirmed that N doping reduced the number of -OH groups on the N-doped composites. Additionally, fluorination of N-F co-doped TiO2 and bentonite surfaces inhibits hydrogen bonding and π-π interactions between the TC and the composites. As the N doping ratio increased, the coverage of N-F co-doped TiO2 on the composite surface increased, resulting in the TC adsorption decrease with the increases N doping ratio.
