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
Figure 9
Four repetitive DPVs of 0.5 μM AC on the surface of oppy/MWCNT/GCE during (a) one day and (b) four days. Potential sweep rate was 100 mV s−1 and supporting electrolyte was 0.1 M phosphate buffer solution of pH 7.0.
