Abstract
A heterogeneous precipitates have been as ion carriers for the preparation of
Na (I) selective membrane sensor. The electrodes give near-nernstian
responses in linear concentration range of IM to IxlO'^M with detection limits
of the order of 10~*M . The stable potentiometric 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 K'^°' ) have been evaluated using fixed interference method. The
sensors have also been as an indicator electrode in commercially available
products.
