Electroanalytical Method

Lead, even in low concentrations, can be dangerous and toxic to humans and their environment. Due to the toxicity of this metal, an electroanalytical method has been developed for the direct quantitative determination of Pb2+. The Pb2+ detection was performed using Differential Pulse Anodic Stripping Voltammetry. The quantification of Pb2+ by these electrochemical methods was carried out on a boron-doped diamondmicro electrode in HNO3 medium (0.01 M). This work made it possible to efficiently detect lead with a detection limit equal to 0.052 μM and a quantification limit equal to 0.173 μM. This method made it possible to selectively detect and quantify the Pb2+ in the presence of other metals such as Cd2+ and Cu2+. In the presence of other metals, a recovery rate of 94.53% was observed. This value is close to the recovery rate obtained (98.6%) when the Pb2+ is alone in electrolyte.
