Voltammetric methods provide a powerful tool for on-site screening and analysis of a wide variety of heavy metals. Although relatively cheap to install and operate, for some metals, it is the only option for on-site determination at, or below, the regulatory limits for drinking water, and the variety of analyte metals is unmatched by alternative on site methods such as colourimetry. However, this very flexibility and the wide variety of methods available can be confusing to users with limited or no experience of voltammetry. This paper reviews some of the factors and options to be considered when selecting from the range of voltammetric methods available.
