“…First, P2 could be adsorbed on the surface of TiO 2 ST-NT@Fe 3 O 4 NPs and removed via filtration prior to the HPLC analysis. Adsorption of various pharmaceuticals on iron oxides has already been described (Olusegun et al, 2023). Therefore, it is likely that in the present work, such a phenomenon exists between iron oxides and transformation products of pharmaceuticals, too.…”

“…Therefore, it is likely that in the present work, such a phenomenon exists between iron oxides and transformation products of pharmaceuticals, too. Alternatively, when Fe 3 O 4 -decorated powders were used, P2 could be degraded via photo-Fenton reactions typical for iron oxide-based materials, and thus it was not detected during the analysis (Punjabi et al, Frontiers in Environmental Chemistry frontiersin.org Olusegun et al, 2023). Two photodegradation mechanisms should be considered for iron oxidesregular excitation of the semiconducting materials and photo-dissolution of iron oxidesand P2 could be more susceptible to the latter, which led to its quick elimination from the system.…”

Herein, TiO2 single-tube (TiO2 ST-NT) powders with and without magnetite Fe3O4 nanoparticles (TiO2 ST-NT@Fe3O4NPs) are presented for the first time as excellent photocatalysts for the degradation of one of the most popular non-steroidal anti-inflammatory drugs (NSAIDs), naproxen (NPX). The TiO2 ST-NT powders were synthesized by anodization followed by etching of the double wall, bending, sonication, ultra-centrifugation, and finally annealing at 600°C. A part of the obtained TiO2 ST-NT powders was decorated with Fe3O4 nanoparticles using a simple one-step decoration process. The best photocatalytic performance of TiO2 ST-NT and TiO2 ST-NT@Fe3O4NPs powders was obtained under the white light (6.2 × 10−4 s-1) and the blue light (2.7 × 10−4 s-1), respectively. During NPX photodegradation using TiO2 ST-NT powders, three main NPX transformation products (P1, P2, and P3) were detected. Upon excitation with the blue light illumination, TiO2 ST-NT@ Fe3O4NPs powders exhibited higher performance (∼80%) than TiO2 ST-NT powders (∼23%) within 1 h, resulting in an approximately three times increased photocatalytic rate constant. Moreover, under simulated sunlight conditions, TiO2 ST-NT powders demonstrated remarkable activity, achieving a 94% NPX degradation within 1 h. TiO2 ST-NT and TiO2 ST-NT@Fe3O4NPs powders represent excellent photocatalysts for NPX degradation.

The discharge of wastewater from the pharmaceutical industry poses risks of detrimental effects on various ecosystems. The presence of hazardous substances in pharmaceutical wastewater is a matter of global concern due to its association with multiple disorders, including disruptions in endocrine hormones and significant chronic toxicity. As research in this field continues to grow, the valorization to nanotechnology‐based treatment of industrial wastewater approaches. One prominent focus of recent research is the utilization of nanomaterials, particularly carbon nanotubes (CNTs), in treating pharmaceutical wastewater, aligns with the goals of sustainable development. CNTs demonstrate potential in efficiently mineralizing pharmaceutical compounds in wastewater, offering cost‐effectiveness, ease of handling, and efficacy. Additionally, CNTs possess the capability to remediate pharmaceutical wastewater at a relatively low cost, with the advantage of being recyclable. This review provides an overview of the diverse applications of various CNTs for the removal of pharmaceutical compounds from wastewater, emphasizing the mechanisms of adsorption and degradation of these compounds using CNTs. Furthermore, it sheds light on the application of CNTs in photocatalysis as an economically viable and efficient solution.

“…Briefly speaking, in contrast to pure SLEL-6, the slightly changed peaks of O 1s in CIP@SLEL-6 from 531.01/532.24/533.65 to 530.87/ 531.82/533.34 eV indicated the oxygen-rich groups are capable of promoting the formation of hydrogen bondings, which was further verified by the changes of O 1s in CIP@-SLEL-6/SA beads (Figure S6D). 49…”

Ciprofloxacin (CIP), an important representative fluoroquinolone antibiotic, has been frequently detected in water sources, thus threatening aquatic organisms and human health. In this work, a porous three‐component covalent organic polymer (SLEL‐6) was synthesized through multi‐component (MC) reaction systems for adsorptive removal of CIP from aqueous solution, followed by an encapsulation process to achieve SLEL‐6/sodium alginate (SA) beads with boosted adsorption ability, reusability and recyclability. By virtue of the hierarchical porous natures, functional groups as well as π‐rich skeletons, SLEL‐6 and SLEL‐6/SA beads could deal with CIP contamination effectively. Moreover, the adsorption isotherms of CIP by SLEL‐6 and SLEL‐6/SA beads follow the Langmuir model showing high theoretical maximum adsorption capacities of 57.47 and 163.93 mg g−1, respectively. Furthermore, the plausible mechanisms are proposed according to experimental studies of influencing factors, coupled with characterizations before and after adsorption. This work therefore highlighting the immense potential of COP‐based SA composite beads as new‐type globular adsorbents for eliminating fluoroquinolones from aqueous solution.
