“…For example, graphene-based nanomaterials were utilized to remove antibiotics [18][19][20], which are adsorbed on the material surfaces due to π-π-, electrostatic or hydrophobic interactions, as well as the formation of hydrogen bonds. Highly efficient antibiotic sorption was also observed when using highly porous, surface-active, and structurally stable silica-based materials [21,22], metal oxide nanoparticles [15,23,24], and metal-organic frameworks [25,26].…”

The constant accumulation of antibiotics and their degradation products in wastewater as a result of human activity poses a serious threat to humanity and other living beings. To contribute to solving this important problem, hollow hexagonal boron nitride nanoparticles (BNNPs) with a spherical shape and smooth surface were synthesized, which were characterized as an efficient adsorbent for wastewater treatment from three types of antibiotics: ciprofloxacin (CIP), tetracycline (TC), and benzylpenicillin (BP). As follows from DFT calculations, the interaction of antibiotic molecules (AM) with the BN surface is neither purely physical nor purely chemical, and negative binding energy (BE) indicates that the adsorption process is spontaneous and endothermic. The calculated electron density redistributions at the AM/BN interfaces show that antibiotics interact with BN mainly through oxygen-containing groups. In addition, this interaction causes the BN surface to bend, which increases both the BE and the contact area. The removal efficiency of antibiotics (Re, %) depends on their initial concentration. At an initial concentration of 10 µg/mL, Re50 and Re100 were observed after 24 h and 14 days, respectively. With an increase in the initial concentration to 40 μg/mL, Re50 and Re100 were achieved after 5 and 28 days (with the exception of ciprofloxacin (~80% Re)). The maximum sorption capacity of BNNPs (qe) was determined to be 297.3 mg/g (TC), 254.8 mg/g (BP), and 238.2 mg/g (CIP), which is significantly superior to many other systems. Tetracycline is adsorbed much faster than the other two antibiotics, which is confirmed by both theoretical and experimental data. Based on the results of the DFT analysis, a simple and efficient sorbent regeneration strategy was proposed, which ensures complete removal of antibiotics after 14 (BP), 21 (TC), and 10 (CIP) days. Thus, the obtained results clearly show that BNNPs are promising sorbents for various classes of antibiotics, including aminoglycosides, tetracyclines, and β-lactams.

“…Highly efficient antibiotic sorption was also observed when using highly porous, surface-active, and structurally stable silicabased materials, metal oxide NPs, and metal-organic frameworks. The photocatalysts, which mainly rely on the production of highly oxidizing species such as hydroxyl radical (OH • ) and superoxide anion radical (O 2 − • ), have been considered an effective approach for the degradation of antibiotics in water [86][87][88][89][90][91][92][93][94][95][96][97][98][99][100][101][102][103].…”

In this study, a novel graphitic carbon nitride/cobalt molybdate (g-C3 N4 /CoMoO4 ) nanocomposites (NCs) as a photocatalys was examined during photocatalytic degradation process in the efficient removal of Doxycycline (DOX) from pharmaceutical industry wastewater plant, İzmir, Turkey. Different pH values (3.0, 4.0, 6.0, 7.0, 9.0 and 11.0), increasing DOX concentrations (5 mg/l, 15 mg/l, 30 mg/l and 45 mg/l), increasing g-C3 N4 /CoMoO4 NCs concentrations (1 mg/l, 2 mg/l, 3 mg/l, 4 mg/l, 6 mg/l, 8 mg/l and 10 mg/l), different g-C3 N4 /CoMoO4 NCs mass ratios (5/5, 6/4, 7/3, 8/2, 9/1, 1/9, 2/8, 3/7 and 4/6), increasing recycle times (1., 2., 3., 4., 5., 6. and 7.) was operated during photocatalytic degradation process in the efficient removal of DOX in pharmaceutical industry wastewater. The characteristics of the synthesized nanoparticles (NPs) were assessed using X-Ray Difraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Energy-Dispersive X-Ray (EDX), Fourier Transform Infrared Spectroscopy (FTIR), Transmission Electron Microscopy (TEM), and Diffuse reflectance UV-Vis spectra (DRS) analyses, respectively. The acute toxicity assays were operated with Microtox (Aliivibrio fischeri also called Vibrio fischeri) and Daphnia magna acute toxicity tests. ANOVA statistical analysis was used for all experimental samples. The maximum 99% DOX removal efficiency was obtained during photocatalytic degradation process in pharmaceutical industry wastewater, at 150 W UV-vis light irradiation power, after 180 min photocatalytic degradation time, at pH=9.0 and at 25°C, respectively
