A new. 1‘flicicnt Calcium ion seleciivc electrode has been prepared using Polyurethane nanofibre based ionojihore The prepared tonophore is
.-haiactcnzcd by UV. I T-IR. XRO The sensor exhibits a near Ncmsiian response forCa(ll) ion over a concentration range of 1.0 X 10-8 M tol .0
,M Ihc proixiscd sensors revealed relatively good selectivity and high sensitivity for Ca(ll) over a monova lent cations. It can be used with in the pH
lange of 5 57 to 6 24. The effect of medium and the selectivity coefficient values was evaluated using fixed interference method It was also
successfully used in the analysis o f concentration of Calcium ion in various real samples.
