This paper has presented a novel strategy to carry out direct and sensitive determination of bisphenol A (BPA) based on the graphene modified acetylene black paste electrode (GR/ABPE). This modified electrode was obtained by one-step potentiostatic reduction of exfoliated graphene oxide sheets on the surface of ABPE. Due to the unique structure and extraordinary properties of GR and AB, the fabricated sensor displayed greatly improved voltammetric response to BPA compared with the conventional carbon paste electrode. Under the optimized conditions, the linear range for the detection of BPA was from 0.8 nM to 10.0 nM, 10.0 nM to 8.0 mu M and 8.0 mu M to 0.1 mM, with a detection limit (SIN = 3) of 0.6 nM. Additionally, this newly-developed method possesses some obvious advantages including extreme simplicity, rapid response and low cost. The practical analytical performance of the GR/ABPE was examined by evaluating the detection of BPA in plastic products with satisfied recovery. (C) 2013 Elsevier B.V. All rights reserved.
