Can I detect potassium with a Zimmer and Peacock sensor?

In the adjacent image a Zimmer and Peacock sensor had its working electrode modified with a polymer containing an ionophore specific to the potassium ion,  subseqnetly the sensor was titrated with a potassium salt where the anion was not chloride.


The Zimmer and Peacock sensors, test rigs and potentiostats used to build and test this sensor are linked to in the buttons below.    2021
