In this work low-cost screen-printed transparency electrodes were fabricated and optimized for the simultaneous detection of lead and cadmium using square-wave anodic stripping voltammetry. Bismuth was employed in order to enhance preconcentration of the metals on the electrode surface. Transparency electrodes were integrated in sample vial caps for point-of-use detection, directly on the container where the sample is collected.
