Abstract:
In the present study, a fluorescent sensor L for sensing of Ce 3+ ion was designed and characterized by XRD, 1 HNMR, and FTIR. Its fluorescence behavior towards metal ion was examined by fluorescence spectroscopy. Chelation-enhanced fluorescence was shown by the sensor L upon interaction with Ce 3+ ion. This fluorescent sensor exhibits high sensitivity and selectivity towards Ce 3+ ion in acetonitrile solution, forming 2 : 1 (L : M) complex as determined by Job’s plot. Association constant was found to be 1 × 10 7 M − 1 estimated from the Benesi-Hildebrand plot. No significant interference was observed in the presence of other studied alkali, alkaline, and transition metal ions. A rapid response was observed when employed for the determination of Ce 3+ ion in spiked water samples with a limit of detection equal to 3.4 × 10 − 8 M .
