title: Characterization and utilization of a long-lasting sessile-drop mercury electrode in differential pulse anodic-stripping voltammetric subtrace metal analysis of natural waters.
abstract: Construction details and voltammetric characterization of a long-lasting sessile-drop mercury electrode are reported. The results obtained in the fully automated differential pulse anodicstripping voltammetric determination of cadmium in a simple purified electrolyte as well as of zinc, cadmium and lead in sea-water samples suggest that this new kind of semi-stationary mercury electrode may be employed in voltammetric trace and ultratrace analysis of natural waters for metal ions.
