Voltammetric Measurement of Arsenic in Natural Waters

several U.S.EPA approved methodologies for the determination of arsenic
in ground water. Such technologies are lab-based, time intensive
and can lead to a large capital cost for multi-sample analysis. In
light of the number of sites found to contain arsenic at levels higher
that the maximum contaminant level (MCL), on-site screening and monitoring
systems are an attractive alternative. This review article summarizes
several examples in the recent literature to illustrate the breadth of
work in voltammetric analysis of arsenic in environmental samples.
Included are recent voltammetric results, obtained with a microfabricated
gold array and a field portable potentiostat, at an arsenic contaminated
site in southern New Jersey.
