Abstract

•Graphenated (GR)-polyaniline (PANI) was electro-synthesized on glassy carbon electrode (GCE).•The GR-PANI|GCE functioned as anthracene sensor by electro-oxidation mechanism.•A sensor dynamic linear range of 0.012–1000 μM anthracene was obtained.

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 μM anthracene and a detection limit of 0.0044 μM anthracene were established for the sensor system.
