Three-dimensional fluorescence spectrum and ultraviolet absorption spectrum of Bletilla striata extraction drawn by boiling water were reported.
ultraviolet absorption spectrum
The suitable ultraviolet absorption band is selected via experiment.
This work established the derivative ultraviolet absorption spectroscopy determination of sulfadiazine(SD),sulfamerhoxazole(SMZ) and trimethoprim(TMP) in multi-component sulphonamide recovery rate is 98.2%-99.6%and variation coefficient is 0.26%-0.96%.
