Abstract
The transfer of strontium ion from acidic nitrate media into a series of 1- alkyl-3-methylimidazolium-based room-temperature ionic liquids containing d icyclohexano-18-crown-6 is shown to proceed via cation-exchange, in contras t to conventional solvents such as alkan-1-ols, in which extraction of a st rontium nitrato-crown ether complex is observed.
