【 摘 要 】

An electrochemical sensor based on graphene-polyaniline (GR-PANI) nanocomposite for voltammetric determination of 4-aminophenol (4-AP) is presented. The electrochemical behavior of 4-AP at the GR-PANI composite film modified glassy carbon electrode (GCE) was investigated by cyclic voltammetry. 4-AP exhibits enhanced voltammetric response at GR-PANI modified GCE. This electrochemical sensor shows a favorable analytical performance for 4-AP detection with a detection limit of 6.5 x 10(-8) M and high sensitivity of 604.2 mu A mM(-1). Moreover. 4-AP and paracetamol can be detected simultaneously without interference of each other in a large dynamic range. (C) 2011 Elsevier B.V. All rights reserved.
