Investigation of the Effects of Anode Geometry on the Electrochemical Degradation of Ni-Ethylenediaminetetraacetic Acid Complexes Using Computational Fluid Dynamics Simulation

Boyue Lian et al.

Summary: Anodic oxidation is an effective technology for the degradation of contaminants in wastewater. A three-dimensional computational fluid dynamics (CFD) model was developed to investigate the flow behavior and concentration profiles of Ni-EDTA complexes during anodic oxidation. The results showed that reducing the electrode aperture size enhanced the degradation rate, and a woven electrode exhibited the highest performance. This study provides insights for the optimization of anode design and reactor operation in electrochemical advanced oxidation processes.

CFD simulation of mass transfer in electrochemical reactor with mesh cathode for higher phenol degradation

Linlin Huang et al.

Summary: The study revealed the significant impact of cathode configuration on electro-catalytic activities, showing that a mesh Ti cathode can improve phenol degradation rates by optimizing fluid flow for pollutant transfer. Excellent agreement was found between computational fluid dynamics simulation and experimental analysis, with the mass transfer coefficient of mesh Ti significantly higher than that of planar cathode.

3D-printed highly ordered Ti networks-based boron-doped diamond: An unprecedented robust electrochemical oxidation anode for decomposition of refractory organics

Haichao Li et al.

Summary: A novel 3D boron-doped diamond (3D-BDD) anode was successfully developed through metal printing and chemical vapor deposition, which could efficiently produce more reactive .OH and decompose organic compounds with lower energy consumption and higher removal rates. The through-holes on the BDD electrode promote mass transfer, leading to more .OH generation on 3D-BDD compared to conventional 2D-BDD electrodes. This demonstrates the potential for batch fabrication of customized, rationally-designed BDD anodes with controllable geometries and sizes.

High-efficient decomplexation of Cu-EDTA and Cu removal by high-frequency non-thermal plasma oxidation/alkaline precipitation

Yue Liu et al.

Summary: Organic-heavy metal complexes are challenging to remove by traditional methods, but high-frequency non-thermal plasma oxidation/alkaline precipitation offers an efficient strategy. Cu-ethylene diamine tetraacetic acid (Cu-EDTA) model achieved 98.8% removal efficiency at 6 kV after 10 minutes of treatment with air as carrier gas. Oxygen feeding, Cu2+ concentration, and EDTA concentration affect the decomplexation process, while (OH)· and O2^- in the NTP system play significant roles in the decomposition of Cu-EDTA.

Kinetic Modeling-Assisted Mechanistic Understanding of the Catalytic Ozonation Process Using Cu-Al Layered Double Hydroxides and Copper Oxide Catalysts

Yuting Yuan et al.

Summary: In this study, copper aluminum layered hydroxides and copper oxide were used as catalysts for heterogeneous catalytic ozonation, targeting the removal of oxalate and formate contaminants. The role of the catalyst in contaminant removal was elucidated, with Cu-Al LDHs facilitating slow decay of O-3 to form surface hydroxyl radicals, while CuO rapidly transforms O-3 into surface-located hydroxyl radicals and/or other oxidants. Futile consumption of surface-located oxidants via interaction with the catalyst surface was minimal for Cu-Al LDHs, but becomes significant with higher CuO dosages.
