Abstract
There is provided a solid-contact ion-selective electrode having a high potential stability and potential reproducibility. The ion-selective electrode includes an ion sensitive film having a Group-1 element ion, a Group-2 element ion, a hydronium ion or an ammonium ion as a target ion, an ion occluding material layer, and a conductive electrode, wherein the ion occluding material contained in the ion occludes material layer occluding the target ion, the ion occluding material being a Prussian blue analog represented by the structure formula AM[M'(CN)]□.kHO. Herein, A is one type or a plurality of types of Group-1 elements, Group-2 elements, hydronium, or ammonium; M and M′ are one type or a plurality of types of transition metals; M or M′ includes at least one of nickel, cobalt, copper, silver, and cadmium; □ is a vacancy in a porous coordination polymer; x and y are greater than zero; and a, z, and k are numbers equal to or greater than zero.
