Popis: In this work, a pH sensor based on polyaniline-modified thin-film interdigitated array (IDA) microelectrodes was presented. Aniline was electropolymerized on the surface of IDA working electrodes by means of cyclic voltammetry. Scanning electron microscope and electrochemical measurements were used to characterize the polyaniline-modified sensor surface. Electrochemical impedance spectroscopy (EIS) was finally used to determinate the variation of pH in [Fe(CN)6]3−/4− solutions.
