Abstract
A new, efficient Calcium ion selective electrode has been prepared using Surface modified
Zeolite based ionophore.The prepared ionophore is characterized by UV,FT-IR,XRD..The sensor
exhibits a near Nernstian response for Ca(ll) ion over a concentration range of 1.0 X 10’* M tol ,0
M . The proposed sensors revealed relatively good selectivity and high sensitivity tor Ca(ll) over a
monovalent cations. It can be used with in the pH range of 5.57 to 6.24 . The effect of medium and
the selectivity coefficient values was evaluated using fixed interference method found to give a better
response.. It was also successfully used in the analysis of concentration of Calcium ion in various
real samples.
