This paper describes the use of a polymer-coated thin mercury film electrode for the direct determination of trace metals in body fluids by anodic stripping voltametry. The antifouling properties of the membrane coating greatly improve the analytical signal in comparison with the conventional thin mercury film electrode. Lead in whole blood, urine, and sweat and copper in sweat can be determined accurately with sample acidification as the only pretreatment step, while the determination of copper in serum requires sample deproteination prior to analysis. Owing to an improved procedure for the preparation of the perfluorosulfonated membrane, the lifetime of the electrode is at least one working day when used continuously in acidified body fluids.
