Summary: This paper summarizes the recent findings on advanced oxidation processes (AOPs) for landfill leachate treatment, focusing on the production routes and mechanisms of hydroxyl radical (·OH) and sulfate radical (SO4·-). It also highlights the challenges of using a single advanced oxidation technology for treating special leachates and the potential of synergistic combination with biological or physical methods.

Summary: This study demonstrates the successful immobilization of MIL-88A(Fe) MOF on cotton fibers to fabricate MIL-88A (Fe)/cotton fibers (MC) using an eco-friendly method. The prepared MC effectively activates peroxydisulfate to eliminate tetracycline antibiotics in simulated wastewater under UV-light irradiation. The study also investigates the degradation pathways of the antibiotics and demonstrates the long-term operation possibility of the MC in a continuous photoactivated SR-AOP system using a self-designed fixed bed reactor. The findings highlight the potential use of MOFs in large-scale wastewater treatment.

Summary: Beta-lactam antibiotics are widely used in medicine due to their strong antibacterial activity. They are produced by fungi and bacteria, and their advantages lie in their potent bactericidal activity and wide spectrum of activity. The common mode of action of beta-lactam antibiotics involves inhibiting the synthesis of the bacterial cell wall, leading to the demise of the bacterial cell.

Summary: In this study, a novel kinetic model was developed to enrich the elementary reactions related to transformation products (TPs) in advanced oxidation processes (AOPs). The entire reaction pathways from parent organic compounds to TPs were mapped using density functional theory (DFT). The predicted concentrations of nitro-TPs obtained from the model matched previous research results, confirming the accuracy of the predictions. This research highlights the effectiveness of combining DFT and kinetic modeling in understanding TP formation and decay mechanisms in AOPs.

Summary: The widespread antibiotic pollution, particularly from Erythromycin, poses a serious threat to aquatic environments due to the emergence of ERY-resistance genes and bacteria. Advanced oxidation processes prove to be effective in degrading pollutants like ERY. ERY has been identified as a high-risk macrolide antibiotic by the European Union, and understanding its environmental impact and degradation mechanisms is crucial for tackling antibiotic pollution.

Summary: This study evaluated the feasibility of N-methyldiethanolamine (MDEA) degradation through electrochemical activation of persulfate (PS). The results showed that the dosage of PS, voltage, and initial pH had an impact on the removal rate of MDEA, and the synergistic effect between SO4-. and the three-dimensional electrochemical system increased the removal rate. In addition, kinetic analysis revealed that the degradation process followed a pseudo-first-order model and the reaction rate increased with increasing voltage.

Summary: Beta-lactam antibiotics are effective in treating bacterial infections, but resistance has developed due to overuse and misuse. Resistance is primarily caused by beta-lactamase enzymes that hydrolyze these antibiotics. Bacteria evolve and mutate to produce such enzymes, leading to resistance even against newly discovered antibiotics. Carbapenems are considered the last line of defense, but now resistance is also developing against this combination. This extensive review discusses the different classes of beta-lactamase enzymes, their mechanisms of action, and the role of structural elements in resistance.

Summary: This study retrospectively analyzed the cases of patients with reported penicillin allergy who received beta-lactam antibiotics in the emergency department between 2015 and 2019. The results showed that there were no IgE-mediated allergic reactions after the administration of beta-lactam antibiotics in the emergency department, and the previously reported penicillin allergy did not affect the continuation of beta-lactam antibiotics after discharge.

Summary: In this study, the efficiency of UV-based sulfate radical advanced oxidation processes (SR-AOP) and UV-based advanced reduction processes (ARP) in degrading ciprofloxacin (CIP) in wastewater was investigated. It was found that the UV/PS process was more efficient than the UV/PMS process in SR-AOPs, while the UV/sulfite process was the most efficient among ARPs. The optimal process parameters and the contribution of different reactive species were determined for each process.

Summary: The majority of current wastewater treatment technologies are ineffective in removing pharmaceutical micropollutants, resulting in their discharge into surface water bodies and causing significant harm to fragile ecosystems. The European Commission has published an expansion of legislation for surface water that includes the monitoring and limitation of the discharge of nine pharmaceuticals. Photochemical advanced oxidation processes (AOPs) have shown promise in efficiently removing micropollutants and could potentially reduce the pharmaceutical burden in wastewater. However, there are challenges that limit their widespread use in treatment plants. This review fills the gap in summarizing and assessing the current trends in the utilization of photochemical AOPs for pharmaceutical micropollutant removal in wastewater treatment, representing the first attempt to address this topic.
