Cooperative intramolecular interaction of diazacrown ether bearing beta-diketone fragments on an ionic liquid extraction system.
A novel extractant beta-diketone-substituted diaza-18-crown-6 demonstrated very efficient extraction of Sr(2+) due to an intramolecular synergistic effect on the ionic liquid extraction system and recovery of Sr(2+) from the ionic liquid was successfully achieved under acidic conditions.
