Nafion-Graphene Nanocomposite in situ Plated Bismuth-film Electrodes on Pencil Graphite Substrates for the Determination of Trace Heavy Metals by Anodic Stripping Voltammetry

The use of disposable and inexpensive pencil graphite rods, modified with a Nafion-graphene nanocomposite, in conjunction with an in situ plated bismuth-film is reported as electrochemical sensor for the determination of trace amounts of Zn2+, Cd2+ and Pb2+ in tap water samples. Synthesised graphene...
