“…When light is shone on photocatalysts, photons with energy higher than or equal to the band gap are absorbed, valence band electrons are shifted to the conduction band. The oxidation and reduction reactions that occur are due to the production of electron-hole pairs [4]. Consequently, the kind and intensity of light have a significant impact on the performance of photocatalysis [157].…”

“…Rani et al used a membrane photocatalytic reactor containing suspended TiO 2 photocatalytic particles for naphthalene removal. They studied the impact of different operating parameters such as the initial concentration of naphthalene (5-25 mg/L), photocatalyst loading (0.1-0.9 g/L), and pH (3)(4)(5)(6)(7)(8)(9) on naphthalene removal rate. The maximum naphthalene removal by separate photocatalysis and membrane was 76.8% and 49.1%, respectively, while a naphthalene removal of 90.2%.…”

Environmental pollution has become a worldwide issue. Rapid industrial and agricultural practices have increased organic contaminants in water supplies. Hence, many strategies have been developed to address this concern. In order to supply clean water for various applications, high-performance treatment technology is required to effectively remove organic and inorganic contaminants. Utilizing photocatalytic membrane reactors (PMRs) has shown promise as a viable alternative process in the water and wastewater industry due to its efficiency, low cost, simplicity, and low environmental impact. PMRs are commonly categorized into two main categories: those with the photocatalyst suspended in solution and those with the photocatalyst immobilized in/on a membrane. Herein, the working and fouling mechanisms in PMRs membranes are investigated; the interplay of fouling and photocatalytic activity and the development of fouling prevention strategies are elucidated; and the significance of photocatalysis in membrane fouling mechanisms such as pore plugging and cake layering is thoroughly explored.

“…The production of safe drinking water is one of the most critical issues that has received international attention [1,2]. In addition, it is worth noting that only 1.2% of the world's water supply is comprised of freshwater, and of that, only 0.02% is considered suitable for human use [3].…”

Nowadays, hospital wastewater contains a high concentration of toxic pharmaceutical contaminants, posing a significant threat to the environment, and human and animal life. Cefixime (CFX) is one such toxic contaminant that has a detrimental impact on both aquatic and terrestrial ecosystems. Therefore, it is essential to remove this compound using non-toxic and environmentally friendly procedures to ensure healthy drinking water. In this study, a low-cost and eco-friendly nano adsorbent (nZVI/copper slag) was synthesized and characterized using FESEM, XRD, EDX, FTIR, and zeta potential to remove CFX from wastewater. The Response Surface Methodology (RSM) was used to evaluate the effects of experimental factors including adsorbent dosage (2–10 g/L), pollutant concentration (10–30 mg/L), pH (2–10), and contact time (10–50 min) for efficient CFX elimination. The optimal conditions (adsorbent dosage: 7.79 g/L, pollutant concentration: 19.42 mg/L, pH: 4.59, and reaction time: 36.17 min) resulted in 98.71% CFX removal. The adsorption isotherm and kinetics data showed that the pseudo-second-order kinetics and Langmuir isotherm models were appropriate for CFX elimination. Furthermore, the nano adsorbent demonstrated 90% CFX elimination after up to six repeated cycles in regeneration and reusability testing. Finally, the nZVI/CS nano adsorbent can be an effective and promising solution for removing CFX from wastewater.
