A New Simple Ester Ionophore Based Calcium Ion Selective Electrode – Preparation and its Analytical Application
نویسندگان
چکیده
A new simple efficient calcium ion selective electrode has been prepared using simple ester. A heterogeneous precipitate has been used as ion carriers for the preparation of Ca (II) selective membrane sensor. The sensor exhibits a near Nernstian response for Ca(II) ion over a concentration range of 1.0 x 10 -4 M to 1.0x10 -1 M. The proposed sensors revealed relatively good selectively and high sensitivity for Ca(II)over a mono and divalent cations and anions . It can be used within the pH range of 3.42 to 6.24. The effect of medium and the selectivity coefficient values were evaluated using fixed interference method found to give a better response. It was also successfully used in the analysis of concentration of calcium in various real samples.
