| Abstract: | Objective] To present a method for the determination of heavy mental using differential pulse voltammetry(DPV) with grapheme modified GC electrode. Method] The experiment used electroreduction method to reduce the graphite oxide and tested characterizations of the graphene which modified GC electrode.And the experimental condition for the determination was optimized. Result] Graphene modified GC e-lectrode could simultaneously determine lead,cadmium and copper in food within four minutes,and it presented a precise,stable and jamming-free method. Conclusion] The study can provide reference for rapidly and accurately determining heavy metals in food. |
