The single crystal ion-selective electrode, β-Ag3SI/PVC-THF membrane electrode has showed a linear potential response to the activities of iodide ion (10-1~10-7M). The β-Ag3SI membrane electrode was compared with AgI/PVC-THF membrane and copper metal plate membrane electrodes. In order to measure the selectivity coefficient of the electrodes toward Cl- and Br-, the separation and mixed solution method were employed. The potential-time curve was obtained by the usual immersion technique and pH effect was also examined. The orders of selectivity for Br-, Cl- and stability of response time are β-Ag3SI/PVC-THF membrane > AgI/PVC-THF membrane > copper metal plate membrane. These electrodes could be used as indicating electrodes in the potentiometric titration of a single halide and mixed halides with the standard solution of silver nitrate.
