主　　题：苏丹红Ⅱ 苏丹红Ⅲ 荧光光谱法 同步扫描 

摘      要：A new method of constant-wavelength synchronous fluorescence spectrometry for simultaneous determination of Sudan Ⅱand Sudan Ⅲ was developed with using their fluorescence *** one single scan is needed for effective identification and quantitative determination of the two compounds simultaneously when Δλ=60 nm is *** linear ranges for Sudan Ⅱ and Sudan Ⅲ were 0—3.3 and 0—2.8 μg/mL,*** detection limits for Sudan Ⅱ and Sudan Ⅲ were 14 and 11 ng/mL,*** using this method,Sudan Ⅱand Ⅲ in sausage samples were determined directly with the recoveries of 83.8%—109.5%.
