ملخص المقالة :

The conducting polymer films have been widely applied in the field of electrochemistry owing to their goodstability, permselectivity, unique physical and chemical properties. A novel nano-Au/poly (4-aminobenzoicacid) (PABA) film modified carbon paste electrode was fabricated for sensitive detection of acetaminophenin this paper. The PABA film and nano-Au/PABA film were characterized by scanning electron microscope.The nano-Au/PABA film exhibited obviously catalytic performance to the determination of acetaminophenwith a high sensitivity and a wide linear range. Under optimum conditions (pH, the concentration of 4-aminobenzoic acid, electro-polymerization cycles), linearity between the oxidation peak current and theacetaminophen concentration was obtained in the range of 1.0 × 10–7 – 8.0 × 10–5 mol L-1 with a detectionlimit of 8.0 × 10–8 mol L-1 (S/N = 3). In addition, the nano-Au/PABA film modified electrode wassuccessfully employed to determine the acetaminophen in commercial drugs, and this work has shed somedoubt on the redox mechanism of acetaminophen at the sensor.
