Development of a Nafion-graphene Nanocomposite for Sensitive Electrochemical Determination of Cadmium(II) Ions

摘要

In this study, an extremely sensitive electrochemical platform was prepared for Cd2+ detection using a glassy carbon electrode (GCE) decorated with a Nafion-graphene (Nafion-G) nanohybrid. This strategy was based on accumulation of the metal ions on Nafion-G. Raman spectroscopy, XRD, and FTIR were used for the characterization of the prepared Nafion-G. The behaviour of the Nafion-G was optimized using operational parameters and surface modification. In addition, the sensor we developed was successfully used in the detection of Cd2+ in environmental water specimens.
