DETERMINATION OF COPPER(II) BY ANODIC-STRIPPING VOLTAMMETRY USING A FLOW-THROUGH SYSTEM

Copper(II) has been determined using anodic stripping voltammetry in a flow-through system, The working electrodes consisted of thin mercury films plated on a glassy carbon macrolectrode or microelectrode. Two flow-through cells, based on the wall-jet configuration and the thin-l ayer configuration, respectively, accommodated the working electrodes, Depending on the type of analysis, the flow system could operate on t he flow injection mode or continuous flow mode during the preconcentra tion period, The sequence of operations (mercury plating, metal precon centration, stripping and electrode cleaning) were remotely controlled , The procedures developed were applied to the quantification of Cu-II in different matrices (tap water, acidified sea-water and pharmaceuti cal tablets).
