Abstract :

 A new, efficient strontium ion selective electrode(I) has been prepared using strontium phthalocyanine and electrode(II) was prepared using semicarbazone. A heterogeneous precipitates have been used as an ion carriers for the preparation of strontium (II) selective memane sensor.The sensor exhibits a near Nernstian response for Sr(II) ion over a concentration range of 1.0 X 10–5 M to1.0 X 10–1 M for electrode(I) and for electrode (II) over a concentration range of 1.0 X 10–6 M to 1.0 X 10–1 M. The proposed sensors revealed relatively good selectivity and high sensitivity for Sr(II) over a mono and divalent cations. It can be used with in the pH range of 3 to 5 for electrode(I) and 4 – 6 for electrode(II) . 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 Strontium ion in various real samples.
