Abstract: An anodic stripping voltammetry method was established for fast determination of cadmium content in grain.Samples were dealt with microwave digestion，by using glassy carbon electrodes as working electrode，AgAgCl electrode as reference electrode and platinum electrode as counter electrode for determination of cadmium content in grain.The detection limit of method was 0.4 μgL.A standard adding method was used and average recovery rate was between 100% and 104%.A sample of a certain concentration was determined for 6 times，with a coefficient of variation of 2.43%.This method was stable，rapid and accurate，and could be widely used in emergency monitoring of food safety accidents.
