Abstract
A heterogeneous precipitates have been as ion earners for the preparation of Na (I) selective
membrane sensor This electrode give near-nernstian responses in linear concentration range of 1M
to 1X10 with detection limits of the order of 10 ‘M The stable potentiometnc signals are obtained
with in a short time period ol 3 minutes. The effect of pH. and the effect of medium have been studied
found to give a better response Selectively coefficient values {log „ ) have been evaluated using
fixed interference method The sensors have also been used as indicator electrode in commerciallv
available products
