An electrochemical sensor based on graphene/polyaniline/polystyrene nanoporous fibers modified electrode for simultaneous determination of lead and cadmium

- Electrospun G/PANI/PS fiber with nanoporous surface was firstly developed as an electrochemical sensor.
- Nanoporous structure on G/PANI/PS fiber increases an electroactive surface area, leading to enhanced electrochemical sensitivity of carbon electrode.
- The proposed electrode was successfully applied for simultaneous determination of Pb2+and Cd2+ in river water samples.
