Abstract :
Thin film palladium (Pd) and indium tin oxide (ITO) microelectrodes modify by mercury (Hg) were developed for heavy metal analysis by anodic stripping voltammetry. In case of Pb2+ determination the sensitivity of ITO-Hg array of disc electrodes was higher (130 nA/μM) in comparison with Pd-Hg interdigitated array of electrodes (60 nA/μM).
