| dc.description.abstract | The voltammetric behavior of aniline and anilinium ion has been studied in nitrobenzene as a solvent. T etrabutyl ammonium perchlorate served as a supporting electrolyte in all experiments. In the presence of anilinium ion a cathodic current is observed at about zero Volt, which we believe is due to the reduction of the proton of the anilinium cation. The anodic oxidation of aniline is indicated by a sharp increase in current at about 1 V. The current peak obtained in the first cycle decreases in intensity and at the same time shifts to more positive potentials in the course of successive cycles. At negative potential scans several reduction peaks are observed. A deposit is formed at the electrode which exhibits electrochromic behavior ( blue in the oxidized state and colorless in the reduced state. The deposit has been investigated in sulfuric acid and exhibits a voltammetric behavior similar to polyaniline obtained from aqueous acidic solutions. The results of our investigation show the possibility to obtain polyaniline using aprotic solvent like nitrobenzene. | en_US |
