A new simple method for the preparation of sodium ion selective electrode-its preparation and analytical application
Department of Chemistry, Avinashilingam Deemed University for Women Coimbatore India
A heterogeneous precipitate have been used as ion carriers for the preparation of Na(I) selective membrane sensor. This electrode give near-nernstian responses in the linear concentration range of 1M to 1×10-3 M with detection limits of the order of 10-3 M. The stable potentiometric signals are obtained with in a short time period of 3 minutes.The effect of pH and the effect of medium have been studied found to give a better response.Selectivity coefficient values (log KpotNa,M) have been evaluated using fixed interference method.The sensor have also been used as indicator electrode in commercial products.
