Abstrakt: Quinoline yellow (E104) dye is a food additive and generally used in cosmetics and drugs. In this work, polyethylene glycol hexa decyl ether (Brij 58) was used for the spectrophotometric determination of quinoline yellow (QY) in food and drug samples after cloud point extraction (CPE). Some parameters such as extraction temperature and time, pH, centrifuge speed, Brij 58 (surfactant) concentration, and Na 2 SO 4 concentration were optimized using Box-Behnken design. The limit of detection (LOD) of this method was 0.0019 μg mL -1 for QY while the relative standard deviation (RSD) at low concentration levels (0.03 μg mL -1 ) was 1.32% (n = 5). Findings indicated that, this novel CPE method can be used quickly for the reproducible, selective and sensitive determination of QY dye in ordinary analysis.
