Abstract: A spirocyclic rhodamine 6G hydrazide was used as fluorescence probe to detect glutamic acid and aspartic acid in aqueous solution. Both sample solution emitted 550 nm green light in 1 minute (the excitation wavelength is 500 nm).The detection limit can be as low as 7×10-8 mol/L and 1.4×10-7 mol/L respectively. Finally, the mechanism of selective and rapid fluorescence detection for glutamic acid and aspartic acid was analyzed.

Key words: spirocyclic rhodamine 6G hydrazide, fluorescence probe, glutamic acid, aspartic acid, rapid fluorescence detection
