Generation of hydroxyl radicals in the peroxi-coagulation process with an air-diffusion cathode: Fluorescence analysis and kinetic modeling

J. Trevino-Resendez et al.

Summary: The effect of pH and applied current on the generation of hydroxyl radicals (center dot OH) from Fenton's reaction during peroxi-coagulation treatment was evaluated. Using a fluorescence probe (coumarin) and kinetic modeling, the center dot OH concentration at different current values and the effect of pH on their production were estimated. A system with six ordinary differential equations was solved to predict the concentrations of the main species of Fenton's reaction. The results indicate a positive influence of current increase on center dot OH generation, but a decrease at a higher current due to excessive H2O2 generation and increased pH.

Critical Review on the Mechanisms of Fe2+Regeneration in the Electro-Fenton Process: Fundamentals and Boosting Strategies

Fengxia Deng et al.

Summary: This review provides a comprehensive overview of the mechanisms of Fe3+ cathodic reduction in the electro-Fenton (EF) process. Different strategies to improve the reduction rate are discussed, categorized into electron transfer control and mass transport control. Electron transfer control strategies include creating active sites in carbon and metal-based materials and using emerging techniques like single-atom catalysis or confinement effects. Mass transport control approaches involve magnetic fields, pulse electrolysis, interfacial Joule heating effects, and photoirradiation. Challenges and future prospects are also mentioned. This review aims to clarify the Fe3+/Fe2+ cycling process in the EF process, providing insights for the smart design of highly effective wastewater treatment and valorization systems at an industrial scale.

Role of anodically electrogenerated hydroxyl radicals in minimizing mineral cathodic electroprecipitation in the presence of hard water

Faidzul Hakim Adnan et al.

Summary: Electrochemical systems have been gaining attention in environmental protection, especially in wastewater treatment and reuse, as sustainable processes. However, cathode scaling in wastewater treatment is often overlooked. This study proposes to investigate the anodic contribution to CaCO3 electroprecipitation phenomena under advanced electrooxidation conditions for removing organic biorecalcitrant pollutants. The reaction of hydroxyl radical ((OH)-O-center dot) with carbonates, as well as the anti-scaling effect of local anodic acidification, is discussed in detail.

Summary: The selectivity of NO3- over Cl- in capacitive deionization (CDI) was found to be influenced by operational factors such as charging time, initial concentration ratio, and applied voltage, primarily due to ion-carbon affinity and electrical force. In contrast, membrane capacitive deionization (MCDI) significantly reduced NO3- selectivity due to ion-exchange membrane control based on charge rather than affinity, resulting in a lower NO3- selectivity compared to CDI.
