Development and validation of an anodic stripping voltammeter for remote automatic analysis of heavy metals (Zn, Cu, Pb, Cd) in estuarine and coastal water


The main objective of this project is the development at a prototypic stage of an analytical module for unattended determinations of Zn, Cu, Pb, Cd at trace levels (0.5 - 10 ug/l) in coastal seawater. The module will be based on electrochemical methods.

In a first phase, Square-Wave Anodic Stripping Voltammetry and Absorptive Cathodic Stripping Voltammetry will be evaluated for best results in terms of accuracy, sensitivity, long-term stability, and speciation. Then a module will be designed taking into account all the problems related to automatic operation and remote installation on unsteady containers (buoys and platforms), and will include equipments for water sampling and filtration and reagent accommodation.

An extensive programme of validation exercises will allow the characterization of instruments' performance in laboratory conditions, the optimization of the analytical methods for automatic functioning and required sensitivity, and the verification of the equipment behaviour under real conditions with the prototype installed on a platform.
