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
