Abstract—Sudan red dyes, as illegal food additives, can induce technique for analyzing the characteristics and structures of
carcinoma of bladder. It is important to find out a method to molecules, anic ones. Now, it has a broad
provide an easy, precise and sensitive detection. The aim of our application in biological, chemical, environmental and
study is to obtain the Raman feature frequency excursion of Sudan industrial applications and is widely recognized as a powerful
Ⅰ, Ⅱand Ⅲ, and draw clear Raman spectra. We used the Raman technique for characterizing materials [1-3].
Systems R-3000 spectrometer to detect the solid SudanⅠ(%),
Ⅱ(analytical pure) and Ⅲ(%). Furthermore, we removed the pounds are by far the most widely used synthetic
organic colorants and more than 2000 of such substances are
fluorescence background via curve
