Abstrak

A novel electrochemical sensor, based on a Rh<sub>2</sub>O<sub>3</sub>&#8315;reduced graphene oxide (rGO) composite modified carbon electrode, has been developed for detecting bisphenol A (BPA) in beverages. The prepared Rh<sub>2</sub>O<sub>3</sub>/rGO and its precursor materials were characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD). Under optimum conditions, the sensor presented good electrochemical performance for analyzing BPA, with a linear range of 0.6&#8315;40 &#956;M, detection limit of 0.12 &#956;M, good reproducibility, and excellent stability. The good performance can be attributed to the combination of the good catalytic properties of Rh<sub>2</sub>O<sub>3</sub> and good conductivity of rGO. The sensor is directly used for detecting BPA in the residual solutions of four beverages after simple filtration, with satisfactory recoveries of 93&#8315;99%.
