Cathodic direct current (DC) as well as differential pulse (DP) stripping voltammetry (DPV) enable direct determination of chloride, bromide, as well as iodide ions. The achieved limits of detection for all determined ions are sufficient for practical analytical purposes (tap water, natural water, etc.) and results reported in this paper are fully comparable with results achieved using other electrodes. The possibilities of sample analysis without elimination of the presence of surface-active substances or of dissolved oxygen were studied. The silver composite electrode represents a suitable sensor for analytical purposes and seems to be promising for replacement of electrodes in many cases. Workplace J.
