A Zinc(II) selective electrode based on phenyl disulfide as ionic membrane carrier was prepared. The electrode exhibits a near-Nernstian response for Zn2+ ions over a wide concentration range from (1.0x10-5-1.0x10-1 M) with a slope of 30.1 mV/decade and a limit of detection of 6.2x10-6 M. The response time measured was 15 second .It was found to be selective and useable within the pH range of (3.0-8.0). The life time of membrane sensor prepared could be used for at least 2 months. The electrode was successfully used as an indicator electrode in potentiometric titration of Zinc ions.
