Abstract

The use of an exfoliated graphite (EG) electrode in the square wave voltammetric detection of bisphenol A (a model phenolic pollutant) in water, whereby the phenolic electrode fouling challenge is mitigated, is described. The oxidation peak of BPA was observed at about 0.45 V in phosphate buffer solution at pH 10. The current response exhibited a linear relationship with the concentration over a range from 1.56 µM–50 µM. The detection limit was calculated to be 0.76 µM. The EG electrode surface was renewed after each measurement with excellent reproducibility. A real sample application was also investigated.
