Abstract

The break-point in the Cu(II) titration curve obtained by anodic stripping voltammetry (ASV) is usually attributed to the formation of strong organo-copper complexes. This interpretation is the basis for the direct determination by ASV of the copper complexing capacity of natural waters. The present study suggests, however, that the break in the Cu(II) titration curve in seawater, as determined by ASV, could be due to the formation of a ZnCu intermetallic compound (IC) formed in the mercury during the deposition stage of the ASV procedure.
