摘要：

A novel voltammetric method - anodic - using a bismuth/poly(aniline) film electrode has been developed for simultaneous measurement of Pb(II) and Cd( II) at low mu g L-1 concentration levels by stripping voltammetry. The results confirmed that the bismuth/poly(aniline) film electrode offered high-quality stripping performance compared with the bismuth film electrode. Well-defined sharp stripping peaks were observed for Pb(II) and Cd(II), along with an extremely low baseline. The detection limits of Pb(II) and Cd(II) are 1.03 mgL(-1) and 1.48 mgL(-1), respectively. The bismuth/poly (aniline) electrode has been applied to the determination of Pb(II) in tap water samples with satisfactory results.
