Abstract

The main objective of this work is to provide information on the development of ion selective electrodes (ISEs) based on PVC membrane by incorporating Schiff base ligands and their complexes as ionophores for sensing different metals ion. Ion selective electrodes can be prepared and the electrodes performance may optimized by varying the amounts of PVC, plasticizers and cation/anion excluders. Various characteristic features of chemical sensors with different parameters such as response time, selectivity, lifetime and pH effect on sensor response have been reported. The proposed ISEs have been successfully applied to determine cations and anions and as electrode in potentiometric titrations.
