摘　　要：^(85)Kr是一种重要的核燃料裂变气态产物,具有半衰期长、放射性强的特点。对^(85)Kr气体进行监测检测、回收储存对于人与环境健康、核安全监测均有重要意义,且^(85)Kr在气体示踪、仪表制造、医学诊断等方面均有重要应用。但国内并无提供商用^(85)Kr的产业,只能依靠从国外进口来满足需求。因此,开发裂变气体中^(85)Kr的提取技术具有重要意义。主要综述了Kr/Xe分离方法,并对^(85)Kr提取的相关信息进行了调研。此外对不同技术方法进行对比分析,同时结合国内提取技术的发展现状和国内外差距,对未来工作提出展望。^(85)Kr is an important gaseous fission product of nuclear fuel,which has the characteristics of a long halflife and strong radioactivity.The monitoring,detection,recovery and storage of^(85)Kr gas are of great significance for human and environmental health and nuclear safety monitoring,and^(85)Kr has important applications in gas tracing,instrument manufacturing,medical diagnosis and other aspects.However,there is no domestic industry that provides commerical^(85)Kr,so China can only rely on importing^(85)Kr from abroad to meet its demand,so it is of geat significance to develop an extraction technique for^(85)Kr in fission gas.In this paper,the separation method of Kr/Xe is mainly reviewed,the related information of^(85)Kr extraction is investigated,different techniques and methods are compared and analyzed,and the prospect for future work is put forward in combination with the development status of domestic extraction technology and the gap at home and abroad.
