Abstract

On the basis of Graphene (GR)’s unique single atomic layer structure, the author adopted drop casting method to prepare GR/HGCE, to represent the chemical behavior of Sudan Red I on GR/HGCE, the results show that the GR can effectively improve Thermal Glassy Carbon Electrode (HGCE)’s effective surface area and improve the surface properties of the electrode, the modified electrode has good catalytic activity to Sudan red I. The study established the new method with GR/HGCE for detection of Sudan Red I. This method was used to measure the content of Sudan Red I in the actual samples and the average labelling recovery is 101.4%.
