Synthesis, Characterization and Degradation of Bisphenol a Using Ce-Doped ZnO Nanoparticles in a Fenton-Like System.

Abstract

Bisphenol A (BPA) is a pervasive endocrine-disrupting compound (EDC) with low water solubility, raising significant environmental concerns due to its persistence and toxicity. This study explores the synthesis of cerium doped zinc oxide (Ce-doped ZnO) nanoparticles via a co-precipitation method followed by calcination for the degradation of BPA. Characterization was conducted using X-ray diffraction (XRD) and Fourier-transform infrared (FTIR) spectroscopy. The photocatalytic activity of the nanoparticles was evaluated through BPA degradation under ultraviolet (UV) irradiation. Degradation efficiency was monitored using UV-Vis spectrophotometry at 1050 nm for 200 minutes, showing a reduction from 10 ppm to 2 ppm, with 97% degradation achieved within 120 minutes. The findings indicate that Ce-doped ZnO nanoparticles possess significant photocatalytic potential, offering a promising solution for environmental remediation.
