Abstract
 We applied a novel fluorescent indicator (i.e., fluoroionophore) for industrial wastewater to determine Zn2+ by using fluorescence spectroscopy. The fluoroionophore showed red-shifted fluorescence upon Zn2+ binding. The indicator exhibited ratiometric fluorescence spectral change with increase of Zn2+ concentrations. Zn2+ was successfully determined in real industrial wastewater matrix by using the fluoroionophore. In this research, we could demonstrate the potential application of fluorescence spectroscopy with the fluoroionophore to determine heavy metal ions in real wastewater.
