Anodic stripping voltammetry with gold electrodes as an alternative method for the routine determination of mercury in fish. Comparison with spectroscopic approaches

“…Even if voltammetric methods are the most commonly reported, some potentiometric methods have also been developed for Hg determination (Clevenger, Smith, & Winefordner, 1997). Other authors suggest the use of anodic stripping chronopotentiometry because of the low contribution of capacitive current to the measured signal in comparison to ASV (Kurmaz & Gultyai, 2010). Some reported ASV methodologies are based on the use of simple bare electrodes as working electrode (WE), especially based on carbon and gold.…”
