Fabrication of ZnO Nanorods Supported on Silver Electrode and its Utilization in Potentiometric Measurements

Abstract

On this study we design the simple device that contents two electrodes ( working electrode) and (reference electrode). The reference electrode is a silver-sliver chloride, and the working electrode is zinc oxide nanoparticles which were prepared by ahydrothermal method at low temperature (600 C), also zinc oxide nanoparticles were grown at silver wire. The working electrode and reference electrode were connected by coaxial cable in pH-meter. Then this simple device was used to measure the pH and mV of milk sample.
