Abstract
An analytical procedure is proposed for the direct simultaneous determination in a single scan of Co, Cu, Fe, Ni and V in sediment pore waters by means of adsorptive cathodic stripping voltammetry (ACSV) with mixed ligands (DMG and catechol). Optimum conditions for the determination of these five elements were studied. Detection limits of the technique depended upon the reproducibility of the procedure blank, and were found to be 0.04Â nM Co, 0.09Â nM Cu, 1.29Â nM Fe, 0.46Â nM Ni and 2,52Â nMÂ V making the method suitable for the direct simultaneous determination of these five metals in pore waters, estuarine waters and probably coastal waters.
