Abstract:A new fluorescent probe, N-(2-pyridylmethyl)-1, 8-naphthalimide(PMN) was synthesized and its application for detection of trace Fe3+ in water samples was investigated. The fluorescence intensity of the probe decreased with increasing concentration of Fe3+, while other cations had little or no response on the fluorescence intensity of PMN. In a certain range of 1×10-7~8×10-5mol/L, the fluorescence intensity was linear dependent on the concentration of Fe3+.The method was verified having the advantages of high sensitivity, good selectivity and easy to operate. It was successfully applied to determinate Fe3+ in tap water, well water and domestic sewage samples.
