Abstract
A titanium dioxide electrode using copper(II) ion was developed for measuring glycine. The copper(II)-glycine complex interacted on the titanium dioxide electrode surface. Use of the copper redox system enabled indirect measurement of glycine with good reproducibility without elution of the titanium ion. The calibration curve was determined and the effects of temperature, pH, the scanning rate, concomitant compounds, and the lifetime of the electrode were examined. Under optimal conditions, the current response was linear in the concentration range of 0.02 - 0.10 mM glycine.
