Summary: The ubiquitous presence of PFAS is a major concern due to their bioaccumulation and persistence in the environment. Electrochemical treatment methods, especially utilizing boron-doped diamond and titanium sub-oxide ceramic anodes, show promising results in achieving high removal efficiency of PFAS. However, challenges such as concentration effects and mass transfer limitations need to be addressed for large-scale applications.

Summary: The study demonstrates that electrochemical advanced oxidation treatment with boron-doped diamond anode is effective for the degradation of florfenicol (FLO) in water, showing improved removal efficiency and reaction rate constant with increasing current intensity. The presence of free hydroxyl radicals (OH) and sulfate radicals (SO4-) during the process contributes to faster degradation and higher mineralization of the FLO solution.

Summary: In this study, a solid polymer electrolyte-based system was used for the electrochemical degradation of Chloroxylenol (CXL) in wastewater treatment. The effect of anode material in the electrochemical cell configuration was investigated for the first time. The results showed that the BDD/SPE cell was able to completely degrade CXL even in the absence of supporting electrolyte and in low conductive solutions. The DSA/SPE system became more competitive when NaCl was added. Response surface methodology was applied to optimize the operating conditions for both systems.

Summary: This study investigated the application of a reverse electrodialysis reactor (REDR) in treating synthetic methyl orange (MO) dyeing wastewater. The effects of operation parameters on the chemical oxygen demand (COD) removal efficiency were explored and a mathematical model was developed to predict the variation of COD removal efficiency with treating time under different conditions. The results showed that increasing the fluid velocity and rinse solution flowrate improved the COD removal efficiency and reduced the total energy consumption of the REDR.

Summary: The study developed an efficient electrochemical oxidation (EO) system to remove PFAS from water by reducing the physical resistance of the titanium connector using Boron-Doped Diamond (BDD) and titanium electrodes. The system showed higher removal efficiency for PFOS, PFHxS, and PFOA with low energy consumption due to the reduced resistance. The conductivity with low resistance increased approximately 1.3 times compared to higher resistance levels.

Summary: Advanced oxidation processes are effective in water remediation, but are often limited by high costs. To address this, researchers have developed the DBCER technology to intensify processes and improve sustainability. Through experiments, it was found that DBCER effectively mineralizes phenol and reduces toxicity, demonstrating potential for industrial applications.

Summary: This study proposes a novel boron-doped diamond (BDD) pulse electrochemical oxidation (PEO) technology for efficient removal of levofloxacin (LFXN) from wastewater. The effects of current density, initial pH, frequency, electrolyte types, and initial concentration on the degradation of LFXN were investigated. The study also suggests a possible degradation mechanism of LFXN using Density functional theory calculation and analysis of degradation intermediates. The results show that the proposed method achieved high COD removal efficiency and energy consumption, and provides a promising approach for efficiently treating LFXN antibiotic wastewater without the need for adding H2O2.

Summary: This study demonstrates that electrolysis on boron-doped diamond electrodes is effective in removing PFASs, specifically perfluorooctanoate (PFOA) and perfluorooctane sulphonate (PFOS), from landfill leachates. The presence of long-chain intermediates during electrolysis differed significantly between high and low boron doping concentrations, indicating greater sensitivity of low-doped BDD to the long-chain intermediates of PFOA. This suggests potential for using BDD-electrolysis for PFAS removal despite the presence of competing components in landfill leachates.

Summary: The increasing need for water decontamination under high salinity conditions calls for alternative processes with high efficiency and cost-effective performance, of which electrochemical technologies hold continuous attraction. In this study, a facile and cost-effective TiO2 nanotube (NT) electrode was fabricated to serve as an anode to degrade the selected contaminant under the condition of high sulfate concentration. The degradation performance and mechanism of the selected contaminant were investigated, and the as-made electrodes exhibited excellent performance for the degradation of different contaminants and reliable stability after rounds of use.

Summary: This study investigated the electrooxidation degradation of phenol in different supporting electrolytes (NaCl, Na2SO4, H2SO4). The efficiency of degradation and the impact on the environment were examined with different measurement methods. The results showed that using boron-doped diamond anode achieved higher removal efficiencies and induced more progressive degradation, compared to mixed-metal oxide. The choice of electrolyte affected the degradation pathways and detoxification pattern.
