ABSTRACT:
An improved potassium ion-selective electrode comprises a support having thereon a metal layer, a metal halide layer, an electrolyte layer and a potassium ion-selective membrane layer. The electrolyte layer comprises a mixture of salts, sodium halide and potassium halide at a weight ratio of sodium halide to potassium halide of 1:1 to 19:1, resulting in maintained precision and accuracy of results and improved adhesion between the electrolyte layer and adjacent layers. Preferably, the ratio of sodium halide to potassium halide in the electrolyte layer is approximately 3:1.
