Sažetak
The preparation of an ion-selective electrode by chemical treatment of copper wire and its application for the measurements of copper(II) ions and iodide ions is described. The preparation is based on the chemical treatment of metal surface. The proposed reaction mechanism at the sensing surface, which explain the response of the electrode to Cu2+ and iodide ions, are discussed. The prepared electrode is suitable for direct potentiometric measurements of iodide and copper(II) in batch experiments down to concentrations of 1×10-5 mol L-1. A tubular electrode, prepared in the same way, may be used as a potentiometric sensor in flow-injection analysis setup for Cu(II) and/or iodide determination.
