| Abstract: | Super powers! Uranium(VI) ions can be extracted from aqueous solutions into supercritical CO2 (sc‐CO2) via an ionic liquid phase that contained tri‐n‐butyl phosphate (TBP) as a complexing agent (see figure). This process has potential applications in the nuclear industry for removing actinides from nuclear waste.  |
