Summary: Combining a membrane bioreactor (MBR) and advanced oxidation processes (AOPs), this study aimed to efficiently treat a synthetic wastewater containing emerging pollutants. The results showed that the 10 nm track-etch membrane (TEM) had the highest removal efficiency for emerging pollutants, while the removal efficiency for total organic carbon (TOC) by membranes was low. Complete mineralization of TOC and removal of emerging pollutants were achieved using UV/PS 10 mM /ZVI 25 mg/L for MBR effluents.

Summary: Reduced TiO2 nanotube arrays (r-TNAs) have emerged as promising environmental materials for efficient treatment of persistent organic pollutants (POPs) resistant to conventional biological treatment. r-TNAs possess superior conductivity and solar light absorption, as well as well-organized open channel structures for efficient mass transfer. Additionally, r-TNAs can be grown directly on substrates without the use of adhesives, improving their durability and reusability. This paper provides a comprehensive review of r-TNAs in advanced oxidation processes (AOPs), including their fabrication techniques, appealing properties, and potential applications.

Summary: High-performance water treatment systems based on cavitational processes have gained increasing interest in the scientific community. Hydrodynamic cavitation has been proven as an effective alternative, reagent-free method for treating various pollutants in water. The combination of cavitation with advanced oxidation processes (AOPs) has shown enhanced oxidation capacity and the ability to degrade persistent contaminants. The synergistic effect between integrated technologies in hybrid processes contributes to their improved performance. This review discusses principles, mechanisms, and factors influencing the effectiveness of cavitation-AOP coupling, as well as the economic feasibility of these hybrid techniques in large-scale wastewater treatment.

Summary: An apparatus using UV-visible spectrophotometry was used to monitor electrochemical processes in real-time. This study focused on optimizing the electrochemical activation of persulfate for the decolorization of Acid Orange 7 dye. The research investigated the effects of electrode composition, current density, persulfate loading, and stirring speed on the decolorization rate. It was found that the core structure and functional groups of the dye significantly influenced the decolorization rate, and electrochemically-activated persulfate showed faster decolorization than anodic oxidation, particularly for electron-deficient substrates.

Summary: This study investigates the catalytic reactivity of Bi2+xWO6 photocatalysts in PS-based oxidation processes in the absence of light, and reveals the efficient removal of recalcitrant contaminants through the H-abstraction pathway. Bi2.15WO6 shows high reactivity in the catalytic oxidation of BPA by PS under alkaline conditions. The surface Bi(III) acts as the reactive site for the adsorption of BPA and PS, leading to the formation of phenoxyl radicals and subsequent polymerization to BPA polymers.

Summary: The direct use of Fe-III is more convenient than Fe-II in iron-based advanced oxidation processes (AOPs), but the reduction of Fe-III to Fe-II is a rate-limiting step. Introducing co-catalysts with abundant reducing sites, such as molybdenum disulfide (MoS2), can enhance the catalytic performance of Fe-based AOPs for phenol removal. The results showed that MoS2 effectively facilitated the reduction of Fe3+ to Fe2+ and maintained the Fe2+/Fe ratio, enabling the use of Fe3+ in AOPs.

Summary: The degradation of acid brown 14 (AB14) using ultrasound/ultraviolet for the heterogeneous activation of persulphate and ZnO nanoparticle was studied. The experimental results showed that the highest removal efficiency of AB14 was achieved at high persulphate concentration, acidic pH, low initial dye concentration, and simultaneous ultrasound/ultraviolet irradiations with the presence of ZnO. The kinetic study indicated that the second-order kinetic model provided the best fit for the experimental data. The scavenging test revealed that sulphate radicals were the dominant species during AB14 degradation. This process demonstrated efficient removal of organic dyes from aqueous solutions.

Summary: This study investigated the levels of polycyclic aromatic hydrocarbons (PAHs) in forty brands of edible oils marketed in southwest Iran, and assessed the daily intake and cancer risk associated with PAH exposure. The results showed that the majority of edible oils had PAH concentrations below the maximum allowable limit, except for fluorene and benzo(a)anthracene. Canola and corn oils had the highest residual concentrations of PAHs. The study concluded that the current intake of oil does not pose a cancer risk for Iranian consumers, but regular monitoring and assessment are recommended.

Summary: UV/E-Cl/HNs is a new approach for the degradation of bisphenol A using UV-E-chlorination/hematite nanoparticles as a heterogeneous photocatalytic activation of electrogenerated chlorine, which generates reactive chlorine and oxygen species. Under optimum conditions, a decontamination efficiency of 99.4% was achieved within 40 minutes. The presence of UV irradiation and hematite resulted in the production of oxidative radicals, which played a vital role in the oxidative treatment. The UV/E-Cl/HNs process is environmentally friendly and has potential applications in wastewater treatment.

Summary: This study reports a method using the concurrent activation of periodate (PI) by ultraviolet (UV) and ultrasound (US) to eliminate para-nitrophenol (PNP) from aqueous solution. The results show that complete degradation of PNP can be achieved in 30 minutes. It is found that the presence of ferrous ions increases the degradation rate. Additionally, the performance of the PI/UV/US process is examined on real wastewater and shows the removal of 70% of total phenol in 60 minutes. Although the process is energy-consuming, its excellent performance justifies its scaling up.

Summary: Mn2O3/Fe2O3 (MFO) was synthesized and used to activate monopersulfate (MPS) for the degradation of ciprofloxacin (CIP). The effect of various parameters on CIP degradation was studied, and under optimized conditions, approximately 92% of CIP was decomposed. Inhibitory effects were observed with nitrite, phosphate, and bicarbonate ions, while chloride and nitrate ions had neutral effects. MFO exhibited high catalytic activity and sulfate radicals played a more significant role than hydroxyl radicals.

Summary: Designing defects-rich hollow heterostructure bimetal sulfides is an efficient strategy for accelerated monoper-sulfate (MPS) activation. The mono-step sulfidation method was used to develop sulfur vacancy (SV)-rich hollow oxygen-doped Co9S8/Fe7S8 (O-CSFS), which exhibited superior performance due to the highly elec-troactive sites induced by SV and oxygen doping, low charge resistance, and increased conductivity. The ROS-driven pathway and ET-driven pathway were found to be responsible for PCM degradation in the O-CSFS/MPS system, with the ET-driven pathway playing a more significant role.

Summary: Sulfate radical-based advanced oxidation processes (SR-AOPs) are being recognized as an effective alternative for removing persistent pollutants in water. Persulfates, such as peroxydisulfate (PDS) and peroxymonosulfate (PMS), are commonly used sulfate radical donors. UV-activated PDS and PMS can efficiently degrade anthraquinone dye (AB129) and inhibit the formation of by-products. This research demonstrates the reduced ecotoxicity of treated water after degradation, confirming the environmental friendliness of sulfate radical-based processes.
