Effects of background electrolyte and oxygen on trace analysis for lead and cadmium by anodic stripping voltammetry

L'analyse de ppb de plomb et de cadmium par voltammetrie de redissolution anodique avec impulsions differentielles en milieu acide est affectee par les quantites d'ions chlorures et d'oxygene dissous dans la solution. L'oxygene dissous sous forme moleculaire ou H 2 O 2 affecte seulement l'etape de redissolution
