Abstract
A heterogeneous precipitate have been used as ion carriers for
the preparation ofNa(I) selective membrane sensor. This electrode give
near-nernstian responses in the linear concentration range o f IM to
] X10'^ M with detection limits ofthe order of 10'^ M. The stable potentiometric
signals are obtained with in a short time period of 4 minutes.The effect
o f pH and the effect of medium have been studied found to give a
better response selectivity coefficient values (log ) have been
evaluated using fixed interference method.The sensor have also been
used as indicator electrode in commercial products.
