Voltammetric determination of mercury(II)

Monitoring mercury provides a real challenge in analytical and environmental science, yet solutions are urgently needed due to the adverse effects of mercury on human health and the environment. Electrochemical techniques, more specifically voltammetric techniques, for determination of mercury(II) [Hg(II)] have inherent advantages. We review the state of the art in voltammetric determination of Hg(II) through quantitatively comparing different approaches classified according to the type of working electrode used. As much modern electroanalysis uses nanomaterials for the design of optimal electrode surfaces, this aspect is covered fully. (C) 2013 Elsevier Ltd. All rights reserved.
