A Schiff base 5-Methoxy-N-(2-pyridylethylsulfanylethyl) salicylideneiminate (MPES) have been used for the construction of PVC based ion-selective electrode. Fixed interference method was used to determine the selectivity of the proposed electrode. The membrane components of the electrode were optimized by using different plasticizers. The membrane electrode with composition of BEHS: PVC: MPES: Anionic additive i.e. 65%:32%:2%:1% (w/w) respectively has a detection limit of 4.6 x 10-11 M in a concentration range of 2.1 x10-10 M to 1.0 x 10-1 M with a Nernstian slope of 33.5 1.0 mV/ decade of activity. The proposed membrane electrode no.7 works satisfactorily in a pH range of 1.5-6.8 with a response time of ~5s. The effect of various internal solutions, ionic and non-ionic surfactants on the potential response of the electrode was also studied.
