摘要：

A fluorescent enhancement probe(for short: NCFP) was designed and synthesized based on the naphthalene imide derivatives grafted chitosan through imidization, schiff base reaction, and so on by using 1, 8-naphthalene anhydride, chitosan, moroxydine hydrochloride as raw materials. The structure of the fluorescent probe was characterized by 1H NMR, FI-IR method, the spectral properties and identification of metal ions were studied with fluorescence spectroscopy. The results indicate that the fluorescent probe has strong fluorescence responses to Al3+, and remarkably high selectivity to Al3+ than other metal ions. When the concentration of Al3+ is in the range of 29.90-253.41 μmol/L, there is a good linearity between the fluorescence intensity of the probe and the concentration of Al3+. Linear correlation coefficient R2=0.997 9, the detection limit of the probe is 4.279 μmol/L to Al3+. The complexation ratio of probe/Al3+ is 1: 1 from the method of Job's plot by fluorescence pectrophotometry. © 2018, Science Press. All right reserved.
