Paper Abstract

Carbon nanotube membrane (CNTM) has been employed as the counter electrode in a two-electrode voltammetric electronic tongue system. Owing to its large surface area, CNTM provides significant double layer capacitance at the solid/solution interface, and offer a constant potential during the electrochemical detection. In order to characterize the analytical possibilities of the electronic tongue system, hydrogen peroxide has been detected. Principal component analysis (PCA) is used for identification. From the PCA plots, the electronic tongue system by using CNTM counter electrode shows much better performance and more promising than the conventional voltammetric two-electrode electronic tongue system by using large surface stainless steel counter electrode.
