Abstract

The fluorescence probe for Mg

was prepared with 2-amino benzene and imidazole and 7-hydroxyl coumarin as the basic raw material. The product composition was characterized in detail by means of nuclear magnetic resonance spectrum and mass spectrum

and then through the test and analysis by fluorescence emission spectrum

the various properties of the probe were understood. The results showed that the probe has good selectivity to Mg

in the mixed solution of MeOH:H

O=1:1(

V:V

) and there are no other metal ions(Ca

) interference. The probe is reversible to Mg

the detection limit is 7.310

-8

mol/L. Through the study on performance of the probe

the probe can complete the detection of Mg

. The probe has potential application value in the fields of biomedical

environmental science and analytical chemistry

etc
