Abstract EN
A simple and easily synthesized fluorescent sensor, Schiff base sensor (SBS), produced by condensation reaction of equal amounts of anthranilic acid and salicyladehyde.
It was synthesized and characterized systemically.
Both UV-vis and fluorescence spectroscopic studies indicated that the SBS sensor showed good selectivity toward the studied ions: Na+, K+, Cu2+, Co2+, Fe3+ , Al3+ and Cr3+.
Whereas, chromium (III) and copper (II) exhibited the largest fluorescence enhancement over the other investigated ions.
Chelation-enhanced fluorescence were shown upon the interaction of SBS sensor with some metal ions studied forming inclusion complexes.
The fluorescent sensor in aqueous ethanolic solution exhibited high selectivity towards Cu2+ and Cr3+ ions, forming 2 : 1 (L : M) complex as determined by Job’s plot.
The formation constants of the inclusion complexes (Mn+/SBS) were measured via spectrofluorometric method applying Benesi-Hildebrand equation.
