| Abstract(in English) | Quick and easy surface-analysis technology has been developed using two electrochemical methods, aiming multi-purpose chemical sensor developments; the surface-polarity controlling method and cyclic voltammetry. Aromatic compounds, amine and alcohol were measured using the surface-polarity controlling method. As a result of principal component analysis, responds of these compounds located in the region different each other for benzene rings, amino groups and hydroxyl groups respectively. Changes of impedance after cleaning has been suggested that adsorption of aromatic compounds on Pt surface is irreversible. The adsorption was confirmed using cyclic voltammetry in 0.5 M H_2SO_4. Continuous cyclic voltammograms indicated that a gradual decrease of adsorbate coverate was observed, and the clean Pt surface could be recovered. |
