Abstract
A heterogeneous precipitates have been as ion carriers for the preparation of Na (I) selective
membrane sepsor. 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 of 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 commerdallv
available products
