Abstract
A method is described for the determination of copper in seawater by a dsorptive stripping voltammetry after accumulation of a 1,2-dihydroxya nthraquinone-3-sulfonic acid (DASA) comples. The effects of various op erational parameters (pH, ligand concentration, potential, and accumul ation time) on the reduction current of the adsorbed chelate are discu ssed. A linear current concentration relationship was observed up to 5 x 10(-8) M. The detection limit is 0.3 nM.
