| Research Abstract |
The aim of this research is removal and luminescence detection of harmful metal ions based on solvent extraction using ionic liquids as extracting media. In this study, a novel extractant diazacrown ether bearing luminescent 8-quinolinol derivative was synthesized, and provided high extraction performance for Cd^<2+> due to an intramolecular synergistic effect on the ionic liquid extraction. Furthermore, the spectroscopic characteristic of this extractant changed through the complex formation with Cd^<2+>, which enabled the quantitative detection of Cd^<2+> concentration.
