摘要

以1，8-萘酰亚胺、壳聚糖、盐酸吗啉胍为原料，通过酰亚胺化、席夫碱等反应，设计合成了一种萘酰亚胺接枝壳聚糖类增强型荧光探针（NCFP）。采用红外、核磁共振等技术对其结构进行表征，利用荧光光谱研究了其光谱性能及对金属离子的识别作用。研究结果表明，合成的荧光探针对Al

具有较高的选择识别性能，且受常见离子的干扰较小。探针的荧光强度与Al

浓度（29.90~253.41 mol/L）有良好的线性关系，线性相关系数

=0.997 9，Al

的最低检出限达4.279 mol/L，Job's曲线表明，荧光探针与Al

的络合比为1：1。

Abstract

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

H 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 Al

and remarkably high selectivity to Al

than other metal ions. When the concentration of Al

is in the range of 29.90-253.41 mol/L

there is a good linearity between the fluorescence intensity of the probe and the concentration of Al

. Linear correlation coefficient

=0.997 9

the detection limit of the probe is 4.279 mol/L to Al

. The complexation ratio of probe/Al

is 1:1 from the method of Job's plot by fluorescence pectrophotometry.
