AI Technical Summary

Technical Problem

Conventional potassium ion-selective electrodes lack stability.

Method used

An all-solid-state potassium ion selective electrode is developed, comprising a conductor with an internal structure covered by a potassium ion-sensitive membrane, where the internal structure contains an active material represented by FeFe and KTP, and optionally includes an intermediate layer with KTP and a conductive component.

Benefits of technology

The stability of the potassium ion selective electrode is enhanced, with improved potential fluctuations and reduced electrode resistance, maintaining sensitivity and detection limits.

Abstract

To provide a highly stable potassium ion selective electrode.SOLUTION: The all-solid-state potassium ion selective electrode includes: a conductor; an internal structure formed on the surface of the conductor; and a potassium ion-sensitive membrane covering the internal structure. The internal structure contains an active material expressed by a structure formula of KxFeFe and KTP; in which x is a number greater than 0 and less than or equal to 2.SELECTED DRAWING: Figure 1
