Abstract
A simple and rapid method for determination of lead in blood by differential pulse stripping voltammetry (DPS) without preliminary mineralization of the sample, is described. Lead determination was performed in native samples of blood in the electrolyte of Britton-Robinson buffer (pH 5–5.5). The proposed method is shown to be reproducible and in good agreement with the reference technique AAS used on mineralized blood samples. Our results indicate that differential pulse stripping voltammetry is a reliable, rapid and highly sensitive method for blood lead analysis.
