Sowmya 1 Department of Chemistry, Avinashilingam University for women, Coimbatore - 641043 (INDIA) <p style="text-align: justify;">A heterogenous precipitate have been as ion carriers for the preparation of Lead(II) selective membrane sensor. The electrodes give near-Nernstian response in the linear concentration range of 1M to 1x10<sup>-6</sup> M with detection limits of the orders of 10<sup>-6</sup> M. The stable potentiometric signals are obtained with in a short time period of 3 seconds. The effect of pH and the effect of medium, have been studied, found to give a better responses Selectivity coefficient values (log K&nbsp;) evaluated using fixed interference method. The sensors have also been as an indicator electrode in potentiometric titrations of lead(II) ions with EDTA and its determinations in alloys.</p> <p>&nbsp;</p> <p><em>Key words:</em> (II), Araldite-matrix, Selective membrane sensors.</p> https://journalofchemistry.org/paper/678/ Lead Araldite-matri Selective membrane sensors
