摘要
电容去离子(CDI)是一种装置结构简单、无二次污染、能耗低的新型水处理技术,被应用在海水淡化、苦咸水脱盐和废水处理等方面。文章分析了CDI的工作原理,从电极材料的比表面积、导电性能和盐吸附容量等方面综述了基于双电层理论的碳质材料和基于法拉第反应的赝电容材料,阐述了不同电极材料在掺杂和改性等操作修饰后对脱盐性能的影响,为当前研究提供理论基础和研究思路。
Capacitive deionization(CDI)is a new type of water treatment technology with simple device structure,no secondary pollution and low energy consumption,which is applied in seawater desalination,brackish water desalination and wastewater treatment.The working principle of CDI technology is analyzed and reviews carbon materials based on electric double layer theory and pseudocapacitive materials based on Faraday reaction in terms of specific surface area,conductivity and salt adsorption capacity of electrode materials.The effects of different electrode materials on the desalting properties after doping modification are described,which provides theoretical basis and research ideas for current research.
