Abstract: The electrochemical preparation of novel poly(4-amino-2,1,3-benzothiadiazole) films on a platinum surface in sulfuric aqueous medium by cyclic voltammetry is described. The resulting polymeric electrodes were characterized by FT Raman spectroscopy, scanning electron microscopy and potentiometry. Spectroscopic measurements confirmed the participation of the amino group and sulfur atom in the process that forms the granular structure of poly(ABTD). Potentiometric results showed the response of the poly(ABTD) film towards divalent cations such as Zn2+ and Cd2+ in the concentration range from 10−7 up to 10−2 mol L−1. A cooperative combination of the cation-sensitive poly(ABTD) electrodes in an array with pH- and anion-sensitive electrodes was able to recognize different Czech beers.
