| titleOfInvention | Ratio type fluorescent probe for detecting divalent lead ions and preparation method thereof |
| abstract | The invention discloses a ratio type fluorescent probe for detecting divalent lead ions and a preparation method thereof, belonging to the technical field of fluorescent probes, wherein the ratio type fluorescent probe is named as 2, 2' - (1,3, 4-oxadiazole-2, 5-diyl) bis [ N- (3-carboxyl propionyl) aniline ], is prepared by reacting 2, 5-bis (2-aminophenyl) -1,3, 4-oxadiazole with succinic anhydride, and the ratio of the fluorescence intensity at 432nm to the fluorescence intensity at 383nm and the concentration of lead ions are in a linear relation in a certain range. The probe has high detection speed on lead ions, the response time is only 17 seconds, and meanwhile, the interference of other metal ions on the detection is small, so that the probe is an ideal lead ion rapid detection sensing probe. |
