ABSTRACT
Ensembles of gold nanodisk electrodes (NEE - Nano Electrodes Ensemble) 30 nm in diameter are presented, focusing on their capability of furnishing improved signal/background current ratios with respect to conventional electrodes. NEEs are employed here for the voltammetric determination of iodide concentration in samples of interest in marine environmental studies. Specifically, NEEs are applied to determine directly the iodide at micromolar concentration levels in iodized edible salt by cyclic voltammetry as well as at sub-micromolar concentration levels in lagoon waters by square wave voltammetry.
