- Abstract
A nanoelectrode array of vertically aligned carbon nanofibers was used for the determination of trace heavy metal ions by anodic stripping voltammetry. Pb2+ was used as a representative system in this study providing well-defined stripping voltammograms. A detection limit of 56.44 nM for lead was obtained which is well below the environmental requirements. The detection sensitivity is 3500 to 11,800 mA/M depending on the density of the nanoelectrode array. The attractive behavior of the carbon nanofiber electrode provides a safe and nontoxic alternative to the mercury electrodes commonly used in electrochemical stripping analysis.
