Voltammetric Determination of Acetaminophen in  the Presence of Codeine and Ascorbic Acid at Layer-by-Layer MWCNT/Hydroquinone Sulfonic Acid-Overoxidized Polypyrrole Modified Glassy Carbon Electrode

<table>Cyclic voltammograms of 1 mM AA in phosphate buffer solution of pH 7.0 on the surface of various electrodes; bare GCE (solid line), CNT-GCE (dotted line), and oppy/MWCNT/GCE (dashed line). Potential sweep rate was 100 mV s<sup>−1</sup>.</table>
