Abstract: | Abstract Graphene foam is one kind of network of three dimensional (3D) graphene, which inherits the properties of two dimensional graphene and overcomes the aggregation/stacking of graphene sheets. In this work, graphene foam has been characterized by scanning electron microscopy and Raman spectroscopy. A graphene foam electrode was evaluated as a new electrode material by cyclic voltammetry (CV) and used for the detection of trace level of Pb2+ by anodic stripping voltammetry (ASV). Under the optimized condition of deposition potential (1.2V) and deposition time (2min), the detection limit is estimated to be 40 nM for Pb2+ based on the 3Ã method. |
