Abstract:

 A conducting polymer have been as ion carriers for the preparation of potassium ion selective membrane sensor. The electrodes give near nernstian responses in the Linear Concentration range of 1 M to 1x10-2 M with detection limit of the order of 10-2 M. The stable potentiometric signals are obtained with in a short time period of 10 seconds. The effect of pH and the effect medium have been studied found to give a better response. Selectivity coefficient values Kpotpotassium have been evaluated using fixed interference method. Thermodynamic functions such as DGo, DHo and DSo have also been evaluated. The sensors have also been used as indicator electrode in commercially available products.
