Electro-oxidation of anthracene on polyanilino-graphene composite electrode

A novel graphenated-polyaniline (GR-PANI) nanocomposite sensor was constructed and used for the determination of anthracene. The direct electro-oxidation behavior of anthracene on the GR-PANI modified glassy carbon electrode (GCE) was used as the sensing principle. The results indicate that the response profile of the oxidation of anthracene on GR-PANI-modified GCE provides for the construction of sensor systems based on amperometric and voltammetric signal transductions. A dynamic linear range of 0.012-1000 mu M anthracene and a detection limit of 0.0044 mu M anthracene were established for the sensor system. (C) 2014 Elsevier B.V. All rights reserved.
