A heterogeneous precipitates have been as ion carriers for the preparation of chromium (III) selective membrane sensor. The electrodes give near-Nernstian responses in linear concentration range of 1M to 1x10-4M with detection limits of the order of 10-4M. The stable potentiometric signals are obtained with in a short time period of 5 seconds. The effect of pH, and the effect of medium have been studied found to give a better response. Selectively coefficient values (log K pots.) evaluated using fixed interference method. The sensors have also been as an indicator electrode in potentiometric titrations of Cr (III) ion with EDTA and its determination in alloys and wastewater samples.
