In recent years, the research of ionic liquids in the extraction of metals has attracted widespread attention and mainly focuses on two aspects, one is hydrophobic ionic liquids as ‘green’ solvent for the extraction of metal ions; the second is task-specific ionic liquid with functional group as extractant for metal ion extraction. The later is the hot-topic area currently. This paper reviewed the research about task-specific ionic liquid extraction and separation of radioactive metals, heavy metals and rare earth metals etc. in recent years, and its future development was prospected.

Key words: task-specific ionic liquids, extraction, metal ions
