The electrochemical reduction of sunset yellow at a multiwalled carbon nanotube (MWCNT)-modified glassy carbon electrode is investigated using cyclic voltammetry. A simple, sensitive, and inexpensive method for determination of sunset yellow in soft drinks is proposed and the accuracy and reproducibility of this determination method are evaluated. This method is satisfactorily applied for the determination of sunset yellow in soft drinks in the concentration range of 1.2–125.0 mg L–1 and 125.0–265.0 mg L–1, with a detection limit of 0.5 mg L–1.
