Sensitive Determination

The iron oxide/graphene (Fe3O4/rGO) nanocomposite modified electrode and the electrochemical properties of Sudan I were investigated. It was found the anodic peak current of Sudan I was linear with the concentration of Sudan I from 0.008 μM to 6 μM with a detection limit of 0.0005 μM (S/N=3). The regression equation was: Ipa (μA)=-0.8151-0.9651c (μM), R=0.9934. It was convenient and excellent sensitive electrochemical method for Sudan I determination. This electrochemical method was successfully applied to determine Sudan I in food samples.
