Abstract
Optimizing electroosmotic efficiency through enhanced electrochemical reactions has garnered significant attention in recent research. This study pioneers the integration of magnetic field technology within electroosmosis framework to reduce interface resistance and improve efficiency, deriving its theoretical basis from comprehensive magnetoelectrochemical studies. Experiments confirm a substantial effect of magnetic fields, pinpointing the anode as the optimal location for application. Specifically, the magnetic field drastically lowers interface resistance and sustains a high current, facilitating increased electrochemical reaction rates. This improvement is theoretically linked to the Lorentz force generated by the perpendicular intersection of magnetic and electric fields, enhancing ion convection and mass transfer across the soil-electrode interface, a process often hindered by low-permeability soils. Further analysis on the drainage enhancement demonstrates the ability of the anode-arranged magnetic field to significantly increase the drainage capacity and reduce treatment time. Electrochemical parameter analysis corroborates this ability to accelerate the drainage rate by its impact on the electrochemical reactions. In terms of energy consumption, analysis was conducted from multiple perspectives such as interface energy consumption, total energy consumption, and energy utilization rate, proving that strategic placement of a magnetic field at the anode significantly optimizes energy dynamics within the electroosmosis process. Additionally, the deployment of reusable permanent magnets promotes sustainability and cost-effectiveness. These advancements collectively contribute to the potential of magnetic field-assisted electroosmosis in engineering applications. While these developments represent substantial progress, there remains room for deeper exploration. Future research is projected to delve into the intricacies of magnetic field mechanisms and the refinement of design parameters to fortify their application in engineering practices.
