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.
