Abstract
An innovative electrochemical methodology is proposed for the quantitative in situ detection of trace metals in marine environment. This new method uses electrocatalysis to detect the catalyst instead of the substrate of the catalyst. As an example, we demonstrate that peak potential of proton reduction on copper during cyclic voltammetry is an effective method for the accurate detection of copper traces in aqueous media, with a detection limit (LOD) significantly lower than that of conventional electrochemical stripping methods (LOD = 1 nMol/L compared with 40 nMol/L, respectively).
