AbstractThe fluorescent reaction between ascorbic acid(AA) and 2-cyanoacetamide was studied. The experimental results showed that AA can react with 2-cyanoacetamide at pH 12.9-13.3, and form a fluorescent product, which emitted strong fluorescence. The fluorescence intensity was measured at excitation and emission wavelengths of 329 and 380nm, respectively. A linear relationship was obtained between the fluorescence intensity and AA concentration in the range of 0.1-50 mu g/ml, the regression coefficient is 0.9994, and the detection limit of AA is 0.03 mu g/ml.(signal-to-noise=3).
