A novel voltammetric sensor was used for the determination of curcumin by using cadmium oxide nanoparticles‐ionic liquid (1,3‐dipropylimidazolium bromide as a binder) modified carbon paste electrode (CdO‐IL‐MCPE). At pH 7.0 as an optimum electrochemical condition, the oxidation signals for curcumin and vitamin B 9 are separated at ca. 0.41 and 0.73 V respectively; facilitating fast and sensitive analysis of curcumin in presence of vitamin B 9 . The oxidation signal of curcumin represented a linear relationship with the concentration of curcumin (R 2 =0.9981) in the range of 0.2–320.0 µM, with a detection limit of 0.08 µM.
