Abstract

This study presents a comprehensive electrochemical characterization and simulation of anion exchange membranes (AEMs) for water treatment applications, focusing on ion transport behavior. Experimental techniques, including chronopotentiometry, current-voltage (I-V) curve measurements, and electrochemical impedance spectroscopy (EIS), were employed to investigate the kinetics and dynamics of ion transport at the membrane interface. The results were validated and further explored through finite element method (FEM) simulations using COMSOL Multiphysics. The study revealed key insights into the role of membrane resistance, ion diffusion, and capacitive effects on overall membrane performance. Parametric analyses of electrolyte layer thickness, bulk solution concentration, and membrane porosity provided guidelines for optimizing membrane design. The findings highlight the importance of considering these factors in enhancing the efficiency and applicability of AEMs in water treatment processes. Future work will focus on refining simulation models and exploring advanced materials to further improve membrane performance.

水处理阴离子交换膜中离子传输的电化学表征与模拟。

本研究对用于水处理的阴离子交换膜（AEMs）进行了全面的电化学表征和模拟，重点研究了离子传输行为。实验技术，包括时间电位法，电流-电压（I-V）曲线测量和电化学阻抗谱（EIS），研究了离子在膜界面上传输的动力学和动力学。利用COMSOL Multiphysics软件进行有限元仿真，对结果进行了验证和进一步探讨。该研究揭示了膜电阻、离子扩散和电容效应对整体膜性能的重要作用。电解质层厚度、体溶液浓度和膜孔隙率的参数分析为优化膜设计提供了指导。研究结果强调了考虑这些因素对于提高AEMs在水处理过程中的效率和适用性的重要性。未来的工作将集中在完善模拟模型和探索先进材料上，以进一步提高膜的性能。
