The present study describes a new reversed flow injection chemiluminescence method for the determination of the sunset yellow dye in drink samples. This method is based on the dye’s inhibition effect on the emission of chemiluminescence light (CL) generated from the luminol–H₂O₂–Co(II) system, in a way that a decrease in CL intensity is proportional to the concentration of the dye. The linear calibration graph is obtained in the range of 0.15–11.0 µg/mL (R² = 0.9993) and detection limit (LOD) = 0.10 µg/mL. The proposed method was applied successfully for the determination of sunset yellow dye in drink samples, and the results are in reasonable agreement when compared with the reported high-performance liquid chromatography method.

流动注射分析和化学发光检测法用于测定饮料样品中的日落黄（E110）

本研究描述了一种新的反向流动注射化学发光法，用于测定饮料样品中的日落黄色染料。该方法基于染料对鲁米诺-H ₂ O ₂ -Co（II）系统产生的化学发光光（CL）发射的抑制作用，即CL强度的降低与浓度成正比。染料。线性校准图的获得范围为0.15–11.0 µg / mL（R ²  = 0.9993），检出限（LOD）= 0.10 µg / mL。该方法已成功应用于饮料样品中日落黄的测定，与所报道的高效液相色谱法相比，结果吻合合理。
