| Abstract: | A simple and rapid high-performance liquid chromatographic method was developed for the analysis of Sudan dyes in the present study.The effects of the composition of the mobile phase,flow rate and column temperature on Sudan dye separation were tested and the optimal separation conditions were obtained as follows: 100% methanol as the mobile phase,the flow rate of 1.0 mL/min and the column temperature of 30 ℃.The linear ranges for Sudan I～IV were 0.01-40 mg/L with an RSD of less than 5% and a limit of detection of 0.01-0.02 mg/L.The proposed method has been successfully applied to the analysis of Sudan dyes in natural water and food stuffs with satisfactory results. |
