THE THEORETICAL DESCRIPTION FOR THE ELECTROCHEMICAL PYROGALLOL AND HYDROXYQUINOL ELECTROCHEMICAL DETERMINATION OVER CoO(OH)-MODIFIED ELECTRODE

Abstract

The theoretical description for hydroxyquinol and pyrogallol electrochemical determination in food and wastewater has been made in this work. The efficiency of the cobalt (III) oxyhydroxide for this determination is verified from either electroanalytical and electrosynthetical point of view, as it also provides the assisted electro(co)polymerization. The stable steady-state is easy to obtain and maintain, which confirms the efficiency of the electrode modifier and the easy interpretation of analytical signal.
