摘要
A simple electrochemical methodology was described to elaborate a sensor based on poly(1,5-diaminonaphthalene)/reduced graphene oxide film onto platinum-patterned electrodes. The composite electrodes were investigated for Pb2+ determination using square wave anodic stripping voltammetry. Pb2+ was first reduced and preconcentrated onto the modified electrodes at -1.0V, then a positive potential sweep was applied to oxidize Pb-0. A well-defined stripping peak appeared at -0.5V, which was used as analytical signal. The linear detection range was found from 200ngL(-1) to 700 mu gL(-1). Interferences with several other metal ions were evaluated.
