Abstract
A fluorescent probe (L) of di-Schiff base amine ligand was designed and synthesized from 2,6-pyridine-dicarboxylic acid, ethylenediamine and p-hydroxybenzaldehyde by condensation reaction and reduction reaction. The structure was confirmed by means of IR, UV, 1H NMR and MS. The research of fluorescence spectroscopy indicated that the probe L exhibited high selectivity for Ce3+. The spectroscopic titration indicated that A good linear work curve with R2 = 0.99607, the stoichiometry of the Ce3+ complex was 1:1, the minimum detection limits for Ce3+was 3.8382×10-6 mol/L and the binding constant of L to Ce3+ was estimated as 6.3734×107 (mol/L)-1. It was expected to be applied to the detection of trace Ce3+.
