摘　　要：超纯水制备流程一般分为预处理、脱盐、后处理三个阶段,其中脱盐工艺是超纯水制备的核心阶段,脱盐工艺的先进与否对最终的产品水质有着重大影响。该论文综述了纯水的深度脱盐技术,详细介绍了渗透法(RO)、离子交换法、电去离子法(EDI)、电吸附法(EST)等脱盐技术的相关原理及研究进展,并对六种主流脱盐技术的优缺点和适用范围进行了对比评述,在对当前深度脱盐技术在超纯水制备中应用的总结分析的基础上,指出了未来超纯水制备脱盐技术的发展将寄希望于新型脱盐材料的研发和多种脱盐技术联合使用情况下工艺流程的进一步优化。Ultrapure water preparation process usually consists of pretreatment, desalination and aftertreatment. Desalination is core stage of the process,advanced or otherwise,has an important influence on the final quality of water. The paper systematically sum- marized the advanced desalination technology of ultrapure water and minutely introduced the related principle and the achievement in the domestic and overseas of reverse osmosis （ R0） , ion exchange method, electrodeionization （EDI） and electrososorption （EST） ~ Advantages and disadvantages of several kinds of common technology and the scope of application were compared. Based on the a- chievement and application of desalination in ultrapure water preparation ,the author pointed out the trend of improving desalination method ,which is the development of progressive desalination materials and further optimization of using several desalination technologies jointly in progress.
