Anodic Stripping Voltammetry with a Heated Mercury Film on a Screen-Printed Carbon Electrode

This article introduces a new heated mercury film electrode based on a screen-printed carbon substrate. The sensor is easy-to-build and the material costs compared to its iridium-based counterpart are low. The development procedure including electrode construction, mercury deposition and thermal properties is described in detail. As first application, cadmium and lead were determined by square-wave anodic stripping voltammetry with significantly improved signal-to-noise characteristics.
