摘要：

Films of a graphene/copper composite in a copper matrix were deposited on ITO using an aqueous electrolyte solution containing 0.2 M CuSO4 and a graphene oxide suspension at a low current density. Using a further calefaction of the specimens under a flowing hydrogen atmosphere, graphene oxide was reduced. After this, the detection of cadmium(II) using square-wave voltammetry (SWV) on the Cu-graphene/ITO film was illustrated. This approach utilized ion accumulation on the Cu-graphene/ITO film. The performance of the Cu-graphene/ITO film was optimized by surface modification and changing the operating conditions.
