镧系和锕系元素在离子液体中的配位和电化学行为的研究进展

The research progress of coordination and electrochemical characteristics of lanthanide and actinide elements in the room-temperature ionic liquids

高温熔盐电解法是干法后处理的研究重点之一,但高温操作对设备要求和能耗极高,限制了该技术的发展。离子液体作为"新一代绿色溶剂",在室温下就可得到在高温熔盐中电沉积才能得到的金属和合金,具有操作简便、安全、能耗低等优点,有望代替碱金属氯化物熔盐作为熔盐电解技术的介质应用到干法后处理中。在前人工作的基础上概括介绍了近几年来国内外对镧系和锕系元素在离子液体中的配位和电化学行为的研究成果,并展望未来的研究方向。

High temperature molten salt electrolysis technology is one of the most important approaches for dry reprocessing. But this technology often operates at high temperature with high demands for equipment and energy consumption,which limits the development of the technology. Room temperature ionic liquids（ RTILs） are regarded as＂new generation green solvents＂,it can substitute high temperature molten salts for electrolyzing metal and alloy at room temperature,which is easy operation,safety and low energy consumption,it is promising to replace alkali-chloride molten salt as electrolytes applying to dry reprocessing.The recent researcher achievements of coordination and electrochemical behavior of lanthanide and actinide elements in ionic liquid were summarized at home and aboard. And the future research trends are prospected.
