摘　　要：锝-99是核废料中一种常见的放射性元素,由于其高裂变率、长半衰期和高环境迁移性的特点,一旦泄漏到环境中,容易对生态环境造成难以预估的破坏。对目前常用的水中高锝酸盐/高铼酸盐去除方法如萃取法、吸附法和还原法进行了重点介绍,并分析了各自的优缺点。概括了如吸附还原法和还原"固定"法等常用的水中高锝酸盐/高铼酸盐复合去除方法。借鉴其他重金属及放射性元素的去除方法,提出了水中高锝酸盐/高铼酸盐去除方法的发展趋势。Technetium-99 is a common radioactive element in nuclear waste.Due to its high fissionrate,long half-life and high environmental mobility,it once leaks into the environment,it is easy to cause unpredictable damage to the ecological environment.The current commonly used methods for removing pertechnetate/perrhenate from water,such as extraction,adsorption,andreduction,were introduced,and their advantages and disadvantages were analyzed.The commonly used pertechnetate/perrhenate composite removal methods in water such as adsorption reduction method and reduction"fixation"method,were summarized.Drawing lessons from other methods of removing heavy metals and radioactive elements,the development trend of pertechnetate/perrhenate removal methods in water were proposed.
