摘要

含重金属废水污染引起的环境问题已经严重影响到生态系统的功能和人类的生产生活，重金属水污染的解决已成为一个重要的问题。同时，由于HM资源的日益短缺，从工业废水中有效提取和回收有价值的HM资源也引起了研究者的广泛关注。电容去离子（CDI）具有效率高、环境友好、能耗低等优点。近年来，CDI在水处理中的应用越来越多，其在HM分离回收方面的研究也逐年增多。考虑到目前还没有对这一重大课题进行全面而深入的研究。因此，我们对CDI在HM去除和恢复方面的研究进展进行了批判性评价。本文分别对HMs和CDI进行了简要介绍，对CDI中HM离子的选择性分离机理进行了分类，总结了相关应用，分析了存在的问题，并对其未来的应用前景进行了展望。最后，讨论了利用CDI选择性分离和回收重金属离子的障碍和潜力。本文的研究结果将有助于推进CDI在HM分离和回收中的应用，并促进CDI在离子选择性去除领域的深入研究。

Application of capacitive deionization in heavy metal ions removal and recovery: A review

Environmental problems caused by heavy metal-containing wastewater pollution have seriously affected the functioning of the ecosystem and the production and life of human beings, and the solution of heavy metal (HM) water pollution has become an important issue. Meanwhile, due to the increasing shortage of HM resources, the effective extraction and recovery of valuable HM resources from industrial wastewater has also attracted extensive attention from researchers. The advantages of capacitive deionization (CDI) include high efficiency, being environmentally friendly, and low energy consumption. In recent years, CDI has been increasingly used in water treatment, and its research in HM separation and recovery has been increasing year by year. Considering that there is no comprehensive and in-depth review of this significant topic. Therefore, our review critically assesses the research progress of CDI in HM removal and recovery. We provide a brief introduction to HM and CDI, respectively, classify the mechanisms for selective separation of HM ions in CDI, summarize the relevant applications, analyze the existing problems, and anticipate their prospective future applications. Finally, the obstacles and potential of employing CDI for the selective separation and recovery of heavy metal ions are examined. The findings of this review will facilitate the advancement of CDI in HM separation and recovery and promote in-depth research on CDI in the field of ion-selective removal.

期刊介绍： Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
