摘要
Fluorescence spectra and fluorescence quantum yield of aurintricarboxylic acid (ATA) were studied for the first time. It was found that ATA solutions with pH 3 similar to 12 produced fluorescence when irradiated with ultraviolet rays. The maximum excitation wavelength and the maximum emission wavelength are 297 nm and 409 run, respectively. An excellent linear relationship between fluorescence intensity and ATA concentration was observed. The linear range is 0.01 similar to 3 mug/mL, and the detection limit is 0.01 mug/mL. Using quinine bisulphate as a reference, fluorescence quantum yield of ATA was measured to be 0.16.
