Title:
ALL-SOLID POTASSIUM ION SELECTIVE ELECTRODE, AND METHOD FOR MANUFACTURING ALL-SOLID POTASSIUM ION SELECTIVE ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2023/026883
Kind Code:
A1
Abstract:
The present invention relates to an all-solid ion selective electrode comprising an insertion material, and a method for manufacturing such an all-solid ion selective electrode. This all-solid potassium ion selective electrode (1) comprises: a conductor (2); an insertion material (10) formed on the surface of the conductor (2); and a potassium ion-sensitive membrane (20) covering the insertion material (10). The insertion material (10) includes at least a Prussian blue analogue represented by structural formula KxFe[Fe(CN)6]y・nH2O, where x is a number greater than 0 but less than or equal to 2, y is a number greater than 0 but less than or equal to 1, and n is a number greater than or equal to 0.
