摘要：

Copper(II) can be extracted in supercritical CO2 from a room temperature ionic liquid using CO2-philic fluorinated beta-diketonate ligands; thanks to the 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (BMIMTf2N) ionic liquid properties, there is no need to add modifiers to the neat supercritical CO2 to reach high extraction efficiencies.
