The invention discloses a kind of mercury ion fluorescence probe and its preparation method and application based on anthraquinone derivative.One kind is obtained in CH 3 Hg can be used as in OH/HEPES (10 mM, pH=7.4,1/1, v/v) system 2+ Highly selective and high sensitivity fluorescence probe HgP1, probe HgP1 is had studied in CH by Fluorescence Spectrometer 3 To the recognition performance of metal ion in OH-HEPES solution.Result of study shows: probe HgP1 is to Hg 2+ With efficiently single-minded selectivity, there is stronger anti-metal cation and anion interference performance.The probe is limited to 8.2 nM to the lowest detection of mercury ion, shows that this method can meet concerned countries standard to the limitation requirement of mercury ion, has stronger practical application value. |
