The electrodes give nearnemstian responses in linear concentration range of IM to 1 \ 1 0 with detection limitsoftheorderof 10'‘M . The stable potentiometric signals are obtained with in a short time period of 3 minutes. The elTect of pH, and the elTect of medium have been studied found to give a better response. Selectively coefficient values (log ) have been evaluated using fixed interference method. I'he sensors have also been as an indicator electrode in commerciallv available products.A Heterogeneous Precipitate Haset Sodium Membrane Ion Selective Electrode-Its Preparation and Analytical Application
