| Outline of Final Research Achievements |
The extraction of toxic metal ions into an ionic liquid with fluorescent ligands and spectroscopic properties of metal complexes were investigated. In the extraction of lead(II) with the fluorescent ligand bearing monoazadithiacrown ether fragments, the extraction efficiency in the ionic liquid extraction system was enhanced compared with that in the organic solvent extraction system. Furthermore, the fluorescent ligand composed of 8-quinolinol derivative moieties shows strong fluorescence by the complexation with cadmium(II), which enables the detection of trace amount of cadmium(II).
