Development of Anodic Titanium Oxide Nanotubes Applied to a pH Sensor with Amperometric and Potentioimetric Methods

Article Preview

Abstract:

The purpose of this study was to develop the anodized titanium oxide nanotubes (ATONs) as a pH electrode with amperometric and potentiometric method. Titanium oxide nanotubes film was produced on pure titanium piece by titanium anodization at room temperature. The best one ATONs electrode has a linear pH response approximately 53 mV/pH with potentiometric method and 13 A/pH with amperometric method in the concentration range between pH 2 and 12.
