| Abstract: | A method for the determination of Pb and Cd with trace level by stripping voltammetry on the polyaniline electrode modified with Bi particles was investigated. Various kinds of experimental conditions for the determination of Pb and the deposition of Bi particles on the electrode were discussed. The results showed that a stripping potential peak with high sensitivity about Pb or Cd could be achieved, which was similar to that of the modified electrode. Furthermore, the electrode has shown a high stability and a work curve with a fairly good linearity. Meanwhile, a satisfing analytical result of the Pb concentration with trace level in tap water was achieved. |
