砷是一种致癌物质，由于其高毒性，特别是在饮用水中，正受到高度关注。电凝聚法是一种高效、环保的废水除砷方法，具有广阔的应用前景。本文综述了EC法除砷的研究进展，包括主要操作参数的影响、EC性能的优化以及EC反应器结构的评价。系统地讨论了不同电极的EC产品的生产和表征。此外，本文还对EC过程中砷的吸附行为进行了探讨。并对EC与其他工艺的性能进行了比较，提出了EC工艺除砷的研究方向。总体而言，本文的综述将有助于加深对EC脱砷工艺的了解，并为该领域的研究人员提供有用的信息。
Arsenic, classified as a carcinogen, is being subject to high concern due to its high toxicity especially in drinking water. Electrocoagulation (EC) has displayed a great potential as an effective and environmentally friendly method to remove arsenic from wastewaters. This review summarizes the recent development of arsenic removal in EC process including the effects of primary operating parameters, optimization of the EC performance, as well as the evaluation of EC reactor configurations. Production and characterization of EC products with respect to different electrodes are systematically discussed. Besides, this review sheds light on the debate about the mechanism involved in As(III) oxidation and further explores the arsenic adsorption behavior in EC process. Moreover, the performance of EC and other technologies are compared, and future research needs for arsenic removal in EC process are suggested accordingly. Overall, this review will contribute to deepening the understanding of EC process for arsenic removal and offer useful information to researchers in this field.
