Seeja 1 Department of Chemistry, Avinashilingam University for Women, Coimbatore - 641 043, Tamilnadu, INDIA <p>A heterogeneous precipitate have been as ion carriers of the preparation of Nickel (II) selective membrane sensors.&nbsp; The electrodes give near-nernstian responses in the linear concentration range of 1N to 1x10^-5 N with detection limits of the order of 10^-5N.&nbsp; The stable potentiometric signals are obtained with in a short time period of 7 seconds.&nbsp; The effects of pH and the effect of medium have been studied found to give better responses. Selectivity coefficient values&nbsp;&nbsp; evaluated using fixed interference method.&nbsp; The sensors have also been as a indicator electrodes in potentiometric titrations of Nickel (II) ions with EDTA and its determination in alloy analysis.&nbsp;&nbsp;&nbsp;</p> <p><em>Key words : </em>Nickel(II), Aradlite-matrix, .&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</p> https://journalofchemistry.org/paper/649/ Department of Chemistry, Avinashilingam University for Women, Coimbatore - 641 043, Tamilnadu, INDIA Aradlite-matrix selective membrane sensors
