CARVALHO, Leandro Machado de et al. Speciation analysis of arsenic compounds by voltammetric and polarographic methods: a comparative review of their main advantages and applications. Quím. Nova [online]. 2004, vol.27, n.2, pp.261-269. ISSN 0100-4042.

This paper provides a review on voltammetric and polarographic methods for the speciation analysis of inorganic and organic arsenic compounds in different matrices. A discussion on the main advantages of electroanalytical methods in comparison with other analytical methods employed for arsenic speciation is presented. The mechanistic aspects of the most relevant techniques employing cathodic and anodic stripping voltammetry as well as polarographic methods published in the last twenty five years are summarized and discussed. The bibliographic references cited in this work were selected from the Web of Science (published by the ISI) and the main journals of analytical chemistry.

Keywords : arsenic speciation; voltammetry; polarography.
