Spectrophotometric Determination of Sunset Yellow (E-110) in Powdered Beverages and Pharmaceutical Preparations After Cloud Point Extraction Method

Abstract

In this study, for the first time Brij 58 was used for the spectrophotometric determination of sunset yellow (SY) (E-110) in pharmaceutical preparations and powdered beverages after cloud point extraction (CPE). Certain parameters such as pH, surfactant concentration, extraction time and temperature, centrifuge speed and salt concentration were optimized. Linear range in the optimum conditions was 0.01 – 4.00 mg mL-1 and the correlation coefficient was 0.9995. The limit of detection (LOD) and the limit of quantification (LOQ) of this method were 0.0078 mg mL-1 and 0.0261 mg mL-1, respectively.
