All-Solid-State Zn²⁺-Selective Electrodes for Wastewater Measurements

Abstract:

A novel all-solid-state Zn²⁺-selective electrode with a low detection limit was prepared using poly (3-octylthiophene) (POT) as ion-to-electron transducer. The electrode exhibits a Nernstian response for Zn²⁺ ions over a wide concentration range from 10^-3 to 10^-9 M with a low detection limit of 1.0×10^-9 M. Results also showed that the fabricated potentiometric sensors are suitable for the pH range of 3.0 ~7.1 with good stability in harsh conditions.
