Determination of lead in igneous rocks by differential pulse anodic stripping voltammetry at an HMDE.
A versatile and sensitive voltammetric method has been used for the determination of lead in seven USGS standard rocks and in two CRPG (Centre des Recherches Pétrografiques et Géochimiques, Nancy) standard rocks. The results, showing satisfactory precision and accuracy, are discussed with respect to the sample treatment and the voltammetric method.
