The membrane can be worked well over a wide concentration range （1.0 × 106-1.0 × 10-1） M with a slope 29.53 mV/decade and a limit of detection （1.77× 10-7） M. The measured of response time was 9 s. It was found to be selective and useable within the pH range （3.0-7.0）. The lifetime of membrane sensor prepared could be used for at least 4 months. The electrode was successfully used as an indicator electrode in potentiometric titration of palladium ion with EDTA.展开更多
