离子液体中电沉积锕系元素的研究现状北大核心CSCD

在核燃料的干法后处理中,高温熔融盐具有腐蚀性强、能耗大等缺点,而离子液体作为一种低温熔融有机盐,具有熔点低、离子电导率高、电化学窗口宽等优点,被用于回收核燃料中的锕系元素。介绍了离子液体组成、分类及特点,综述了锕系元素(钍、铀、镎、钚、镅)在第一代和第二代离子液体中的电化学行为,总结了离子液体中电沉积锕系元素存在的问题,并展望了该领域重点研究方向。

Research Status of Electrodeposition of Actinides in Ionic Liquids

In the pyroreprocessing of nuclear fuel, high-temperature molten salt has the disadvantages of strong corrosiveness and high energy consumption, while ionic liquid, as a low-temperature molten organic salt, has the advantages of low melting point, high ionic conductivity, wide electrochemical window, etc., and is used to recover actinides in nuclear fuel. The composition, classification and characteristics of ionic liquids are introduced, the electrochemical behaviors of actinides(thorium, uranium, neptunium, plutonium, americium) in the first and second generation ionic liquids are reviewed, the existing problems in the electrodeposition of actinides in ionic liquids are summarized, and the key research directions in this field are prospected.
