“…Carried out studies state that the best performance is associated with the antibiotic removal strategies that involve combined processes [41,46]. They include, for example, a combination of AOPs with biological treatment [43,57] or membrane filtration [42,57]. However, further improvements are needed, mainly in the development of new materials for AOPs [46], in order to make these processes cost-effective while retaining high efficiency.…”

Application of TiO2-Based Photocatalysts to Antibiotics Degradation: Cases of Sulfamethoxazole, Trimethoprim and Ciprofloxacin

2021

The extensive application of antibiotics in human and veterinary medicine has led to their widespread occurrence in a natural aquatic environment. Global health crisis is associated with the fast development of antimicrobial resistance, as more and more infectious diseases cannot be treated more than once. Sulfamethoxazole, trimethoprim and ciprofloxacin are the most commonly detected antibiotics in water systems worldwide. The persistent and toxic nature of these antibiotics makes their elimination by conventional treatment methods at wastewater treatment plants almost impossible. The application of advanced oxidation processes and heterogeneous photocatalysis over TiO2-based materials is a promising solution. This highly efficient technology has the potential to be sustainable, cost-efficient and energy-efficient. A comprehensive review on the application of various TiO2-based photocatalysts for the degradation of sulfamethoxazole, trimethoprim and ciprofloxacin is focused on highlighting their photocatalytic performance under various reaction conditions (different amounts of pollutant and photocatalyst, pH, light source, reaction media, presence of inorganic ions, natural organic matter, oxidants). Mineralization efficiency and ecotoxicity of final products have been also considered. Further research needs have been presented based on the literature findings. Among them, design and development of highly efficient under sunlight, stable, recyclable and cost-effective TiO2-based materials; usage of real wastewaters for photocatalytic tests; and compulsory assessment of products ecotoxicity are the most important research tasks in order to meet requirements for industrial application.

The objective of this study was to summarize the results obtained in a wide research project carried out for more than 15 years on the catalytic activity of different catalysts (activated carbon, metal–carbon xerogels/aerogels, iron-doped silica xerogels, ruthenium metal complexes, reduced graphene oxide-metal oxide composites, and zeolites) in the photooxidation (by using UV or solar radiation) and ozonation of water pollutants, including herbicides, naphthalenesulfonic acids, sodium para-chlorobenzoate, nitroimidazoles, tetracyclines, parabens, sulfamethazine, sodium diatrizoate, cytarabine, and surfactants. All catalysts were synthesized and then texturally, chemically, and electronically characterized using numerous experimental techniques, including N2 and CO2 adsorption, mercury porosimetry, thermogravimetric analysis, X-ray diffraction, Fourier-transform infrared spectroscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, diffuse reflectance UV–vis spectroscopy, photoluminescence analysis, and transmission electron microscopy. The behavior of these materials as photocatalysts and ozonation catalysts was related to their characteristics, and the catalytic mechanisms in these advanced oxidation processes were explored. Investigations were conducted into the effects on pollutant degradation, total organic carbon reduction, and water toxicity of operational variables and the presence of different chemical species in ultrapure, surface, ground, and wastewaters. Finally, a review is provided of the most recent and relevant published studies on photocatalysis and catalyzed ozonation in water treatments using similar catalysts to those examined in our project.

“…Although industries treat their wastewater with conventional processes, these are not e cient in degrading all pollutants, especially emerging organic compounds (EOCs) (De la Cruz et al 2013). EOCs are those organic pollutants that have not been recognized by existing environmental legislation, but it has been shown that these pollutants are affecting aquatic ecosystems and their environment (Bueno et al 2012;Giwa et al 2021;Majumder et al 2019;Phoon et al 2020;Rasheed et al 2019). In the case of antibiotics, studies by Klein et al (2018) found that from 2000 to 2015 their consumption increased by 65 % and that some of these antibiotics are only partially metabolized allowing a fraction of them to be excreted from the body in an unchanged form after consumption (Rasheed et al 2019;Ye et al 2019).…”

One of the most widely used antibiotics is amoxicillin (AMX), which is the most widely used in humans and animals, but it is discharged metabolically due to its indigestibility. Conventional biological and physicochemical methods for removing AMX from water are not enough to mineralize it, only it is concentrated and transferred to produce new residues that require further processing to remove the new residues.In this research, naked and modi ed surfaces with TiO 2 nanotubes (TiO 2,nt ) electrophoretically modi ed with PbO 2 , IrO 2 , RuO 2 , and Ta 2 O 5 were used to evaluate their e ciency in the electrochemical degradation of AMX in acid media (0.1 mol L − 1 H 2 SO 4 ). After their comparison, Pb-Ta 50:50|TiO 2,nt |Ti showed the highest removal e ciency of AMX (44.71 %) with the lowest speci c energy consumption (8.69 ± 0.78 kWh Kg COD − 1 ), and the average instant current e ciency of 26.67 ± 9.19 %, in comparison with the others naked and modi ed surfaces of TiO 2,nt |Ti.
