Abstract:

A new, efficient Calcium ion selective electrode has been prepared using Schiff base based ionophore.The influence of temperature on electrode potential was studied and it can be used in the determination of thermodynamicfunction like ∆G,∆H&∆S.The electrochemical impedance spectroscopy (EIS) technique is also employed to study the electrochemical&surface reactions. It was also successfully used in the analysis of concentration of Calcium ion in various real samples.

Keywords:

Calcium (II); Schiff base; Potentiometry; Electrochemical impedance spectroscopy.
