Özet

A new, green method has been developed for the determination of the trace Sudan I prior to spectrophotometric determination. The ionic liquid, 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF6]), was used as an extraction solvent for Sudan I. The analytical parameters which influence the recovery of Sudan I, such as the pH, ionic liquid volume, and sample volume, were optimized. Sudan I was quantitatively extracted at pH 6.0. The influences of matrix components upon the analysis were investigated. The limits of detection (LOD) and quantification (LOQ) were 0.039 mu g/L and 0.108 mu g/L, respectively. The method was employed to determine Sudan I in food.
