Abstract
A heterogeneous precipitates ha\e been as ion caaiers for the
preparation of Na (I) scicetise membrane sensor. The electrodes give near
nemstian responses in linear concentration range of IM to 1x10'"M with
detection limits ofthe order of 10'\\1. The stable potent iometric 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 have been evaluated using
fixed interference method. The sensors have also been as an indicator
electrode in commercially available products.
