| Abstract: | The concentration of trace vitamin B6 in solid powder flour is detected for the first time by the fluorescence spectroscopy.Through measuring solid barium sulfate samples added with accurate amount of vitamin B6,the emission spectrum with peak wavelength at 405 nm is obtained,and the fluorescence intensity is linear with the concentration of vitamin B6,with a regression coefficient of 0.997 6.According to above method,the emission spectrum of solid flour samples with peak wavelength at 390 nm is... |
