A new simple method for the preparation of Lead ion selective electrode - Its preparation and analytical application
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 1x10-6 M with detection limits of the orders of 10-6 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 ) 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.
Key words: (II), Araldite-matrix, Selective membrane sensors.
