Title:
ALL-SOLID-STATE POTASSIUM ION SELECTIVE ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2024/042855
Kind Code:
A1
Abstract:
The present invention provides a more stable potassium ion selective electrode. An all-solid-state potassium ion selective electrode according to the present invention is provided with: a conductor; an internal structure which is formed in the surface of the conductor; and a potassium ion sensitive membrane which covers the internal structure. With respect to this all-solid-state potassium ion selective electrode, the internal structure contains KTP and an active material that is represented by structural formula KxFeFe, wherein x represents a number that is more than 0 but not more than 2.
