PREPARATION AND INVESTIGATION OF PLANAR SILVER SILVER-IODIDE ELECTRODES

The crystal structure, morphology and electroanalytical properties of planar ion-selective electrodes of layer structure were studied by using AgI as a model. The optimum thickness of the layers was determined in view of the adhesion of the layers and soldering. No significant differences were found in the calibration properties of the electrodes prepared in four different ways. The dynamic studies revealed that the response times of silver iodide electrodes prepared in iodide vapour were significantly shorter than those of the ones prepared electrolytically.
