“…The presence of CuFe 2 O 4 NPs was also indicated by a slight shift to higher diffraction angles, which does not disrupt the cubic structure. 82 Therefore, adding CuFe 2 O 4 NPs resulted in decreased crystallinity and increased porosity. Sharp peaks and little angular variation after magnetic modification demonstrate that the materials remained crystallinity and structural stability.…”

Zeolite/CuFe2O4 nanocomposites (NCs) were synthesized using the coprecipitation technique with different concentrations of CuFe2O4 nanoparticles (NPs) to optimize the capacity of zeolite to cation exchange and study its antibacterial activities. UV–vis, Fourier-transform infrared (FTIR), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy-dispersive X-ray (EDX), Brunauer–Emmett–Teller (BET), and thermogravimetric analysis were utilized to characterize the NCs. XRD patterns revealed a slight shift in the peaks while the amount of CuFe2O4 increased. The CuFe2O4 NPs were distributed uniformly throughout the zeolite framework, and the basic structure of the zeolite was intact, as shown by FESEM and EDX. The addition of 6 wt % CuFe2O4 NPs to the zeolite framework reduced the BET-specific surface area from 336 to 187 m2/g. The thermal stability of the samples increased as the amount of CuFe2O4 NPs increased. Magnetic saturation of NCs was in the range of 10–41 emu/g, indicating suitability for manipulation under an external magnetic field. NCs (6 wt %) demonstrated significant antibacterial activity against different species of bacteria. The efficacy of the antibacterial agent enhanced with increasing the CuFe2O4 NPs, reaching 98% against Escherichia coli. Antibacterial activity was also studied throughout the sequential magnetic separation and recycling phases, and nanocomposite had a strong antibacterial activity after 7 cycles of recycling, making them potentially valuable tools in drug delivery systems, wound healing and tissue engineering, and other biomedical applications.

“…For FONP, the peak at 569 cm −1 corresponds to the Fe-O vibrations in the crystalline lattice of Fe 3 O 4 . 39,40 For FONP@RIP, the characteristic absorption peaks of RIP disappeared and a new peak of Fe-O appeared. Compared with the FTIR spectrum of FONP@RIP, a new peak for OC-O vibration (1415 cm −1 ) appeared in that of FONP@RIP/H 2 O 2 , which could be due to the adsorbed organic pollutants.…”

“…Antibiotic pollution in water resources causes potentially toxic effects on microorganisms, plants, animals, and humans [25]. Many treatment methods such as adsorption [26], membrane filtration [27], oxidation [28], biodegradation [29], reverse osmosis [30], Fenton reactions [31], coagulationflocculation [32] are used for the treatment of antibiotics from wastewater (Table 2). Conventional water treatment technologies including biological treatment, filtration, coagulation, flocculation, and sedimentation have been found to be ineffective in eliminating antibiotics completely [33].…”

Nowadays, antibiotics are extensively used in human and animal medicine. The unconscious consumption of antibiotics and their mixing with water sources without adequate treatment have caused environmental problems. Several chemical and physical treatment methods applied for the removal of antibiotics from aqueous media offer alternative solutions by improving the treatment process and using new materials. As in many areas, nanomaterials are also used in treatment methods such as sorption, degradation, and oxidation. Among the nanomaterials, nano zero-valent iron (nZVI) is frequently preferred in treatment processes due to its abundance, cheapness, ease of application, and high removal performance. Besides its many advantages, nZVI agglomerates in the aqueous phase and exhibits unstable behaviors. This limits the surface area required for antibiotic removal and reduces the removal efficiency. In recent years nZVI has been used in water treatment technologies by being modified with many support materials such as bentonite to minimize particle agglomeration. Bentonite is clay-based support material that provides high removal efficiency and reduces the cost of treatment due to its abundance in nature. In this study, antibiotic pollution and treatment methods in water resources were reviewed and the antibiotic removal performances of bentonite-supported nVZI were investigated. In the studies, it was concluded that the antibiotic removal efficiency increased with the use of support materials.
