Abstract
A full‐automated electroanalytical device is presented here. It is composed of an electrochemically adapted automation module and a competitive screen‐printed sensor modified ex situ by a very low quantity of mercury. The contribution of this automated apparatus to analyses is described in detail. Coupled with an UV‐photolysis unit, it has permitted the rapid detection of both total and electrochemically accessible cadmium in solutions containing 10 mg L−1 of humic substances without addition of reagents. Semicontinuous monitoring of tap water doped with 5.3 μg L−1 of cadmium, in presence of traces of lead and copper, has been successfully achieved for 7 days.
