摘要: 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 an optimum electrochemical condition, oxidation signals and vitamin B9 are separated at ca. 0.41 0.73 V respectively; facilitating fast sensitive analysis in presence B9. The signal represented linear relationship with concentration (R2=0.9981) range 0.2–320.0 µM, detection limit 0.08 µM.
