Abstract
Metallic film electrodes are currently experiencing a major development as environmentally friendly elec-trochemical sensors used in stripping voltammetry. Their development began when attention was drawn to the toxicity of mercury electrodes commonly used as working electrodes in voltammetric procedures. Some of the first non-mercury metallic film electrodes to be developed since 2000, when they were introduced by Wang's team, were bismuth electrodes [1]. The next ones of great interest were lead film electrodes introduced by Korolczuk's team [2]. We wish to propose in this work the use of a film copper electrode for the determination of trace concentrations of lead ions in natural waters. The aim of this work was to optimize the conditions for generating a copper film electrode on glassy carbon as a sub-strate and then to optimize the conditions for concentrating the analyte, which was lead in metallic form, and then to obtain an analytical signal by anodic stripping voltammetry.
