快速的工业化和城市化在水和废水中产生了大量的有害物质，这已经成为环境和公众健康的关键问题。近年来，铁炭微电解技术因其成本低、性能优良而在环境修复领域受到广泛关注。然而，目前还缺乏一个更系统的IC-ME的制备方法，其性能，以及IC-ME在废水修复中的相互作用机制的综述。本文综述了IC-ME材料的合成方法、应用以及IC-ME对污染物的去除机理。目前IC-ME材料的制备方法多种多样，制备方法和条件对IC-ME材料的性能有一定的影响，从而影响其对污染物的去除性能。离子交换微电解去除污染物的机理非常复杂，包括吸附、共沉淀、还原、表面络合和氧化。最后提出了IC-ME应用中存在的问题和研究的空白领域。最后介绍了集成电路在未来应用中需要解决的问题。本文对IC-ME废水修复技术进行了综述和展望，为进一步的科学研究和工程应用提供参考。
Rapid industrialization and urbanization have produced a lot of hazardous substances in water and wastewater, which has turned into a crucial issue to the environment and the public health. Recently, iron carbon microelectrolysis (IC-ME) has attracted extensive attention in environmental remediation due to its low costs and excellent performance. Nevertheless, there is still a lack of a more systematic review on IC-ME preparation methods, their performance, and the interaction mechanisms of IC-ME in the remediation of wastewater. Herein, this work summarizes the synthetic methods, application of IC-ME materials, and the mechanism of pollutant removal by IC-ME. A variety approaches have been applied to prepare IC-ME materials, and the preparation methods and conditions have a certain influence on the properties of IC-ME materials, thus affecting the performance of pollutant removal. The mechanisms of IC-ME for contaminants removal are very complex, including adsorption, coprecipitation, reduction, surface complexation, and oxidation. Moreover, research vacant fields and problems that existed in the application of IC-ME are proposed. At last, the problems to be addressed to adapt IC to future applications are introduced. This paper reviews and prospects IC-ME wastewater remediation technology, which provides a reference for further scientific research and engineering applications.
