Abstract
The present article addressed the fabrication of an efficient electrochemical sensor to analyze bisphenol A (BPA) using Crataegus as an environmentally friendly fuel agent for the synthesis of TbFeO3/CuO nanocomposite. CuO nanostructures synthesized in the presence of Gloriosa superba leaves extract as an alkalizing agent. This novel nanocomposite was used as a modifier and BPA electrochemical behavior examined on the TbFeO3/CuO/Screen printed electrode (SPE) with differential pulse voltammetry (DPV), chronoamperometry, and cyclic voltammetry (CV). Obtained outputs demonstrated improvements in electrochemical response due to the application of the modified electrode. According to the calibration curve, linear ranges were between 0.04 and 300.0 μΜ for BPA and the limit of detection (LOD) was 0.009 μΜ. Finally, this sensor was employed successfully for detecting BPA in the water samples.
