摘　　要：地下及地表水体中的硝酸盐已成为一种普遍存在的污染物。鉴于硝酸盐对动植物及人类健康的长期潜在危害性,从复杂离子混合的水体中有效去除NO_(3)^(-)显得至关重要。然而,Cl^(-)与NO_(3)^(-)在物化性质上具有相似性,两者均属单价盐离子,并具备相同的水化半径。这一特性使得传统脱盐技术在实现二者精准分离时面临极大挑战。鉴于此,本文深入探讨了电容去离子(CDI)和膜电容去离子(MCDI)技术在Cl^(-)和NO_(3)^(-)分离方面的研究进展。通过系统梳理现有文献与实验数据,旨在为读者呈现这两种技术在离子分离领域的最新动态,并对未来Cl^(-)和NO_(3)^(-)的分离技术做出展望,以期为推动相关技术的优化与发展提供理论指导。Nitrates have become a ubiquitous contaminant in both groundwater and surface water.Given the long-term potential hazards of nitrates to flora,fauna,and human health,it is crucial to effectively remove NO 3-from water bodies with complex ionic mixtures.However,Cl^(-)and NO_(3)^(-) share physicochemical similarities,as both are monovalent salt ions with identical hydration radii.This characteristic poses significant challenges for traditional desalination technologies in achieving precise separation of these ions.In light of this,this paper thoroughly investigates the advancements in capacitive deionization(CDI)and membrane capacitive deionization(MCDI)technologies for the separation of Cl^(-)and NO_(3)^(-) .By systematically reviewing existing literature and experimental data,this study aims to present the latest developments in these technologies within the field of ion separation.Furthermore,it provides an outlook on future Cl^(-)and NO_(3)^(-) separation techniques,offering theoretical guidance to foster the optimization and development of related technologies.
