Gowri 1 J. Thamarai Selvi 1 P. Arul Priya 1 G. Shanthi 1 Department of Chemistry, Avinashilingam University for women, Coimbatore - 641043 (INDIA) The [Ni(PPh3) (BPOAP)] complexes have been used as ion carriers for the preparation of Nickel (II) ion selective membrane sensors. This electrode gives near Nerstian responses in the linear concentration range of 1×10-6 to 1 M with electron limits of the order of 10-6M. The stable potentiometric signals are obtained with in a short time period of 5 seconds; the effect of pH and the effect of medium have been studied. Selectivity co efficient values (log <img src="file:///D:/atif/Drive%20E%20data/desktop%20data/Business/journal/JUC/JUC/abs_vol5(2)/AbstrOE1.JPG" style="height:12px; width:20px" />,M ) have been evaluated using fixed interference method (FIM).   https://journalofchemistry.org/paper/698/ Complexes selective membrane sensors
