Abstract
One of the most important organic monomers in the manufacturing of plastic is bisphenol-A (BPA), which is widely used in food packaging, containers, and water pipelines, among other industries. However, because of how easily it contaminates food and water and causes illnesses, including cancer, heart disease, and developmental abnormalities, its extensive usage carries serious dangers to human health and the environment. BPA is nevertheless widely used in numerous products despite its negative effects. A new technique using α-Fe2O3 nanoparticles synthesized from Bluemea sinuate leaf extract is offered to address the requirement for effective BPA detection. The production and composition of α-Fe2O3 nanoparticles were confirmed via rigorous characterization techniques, such as XRD, IR, Raman spectroscopy, XPS, TEM, and UV–Vis spectrophotometry. The nanoparticles showed promising morphology and structure. Then, via electrophoretic deposition, an α-Fe2O3/ITO electrode was created, which showed superior electrochemical qualities for BPA detection. The electrode demonstrated excellent durability and reusability along with great sensitivity (14.4 µA µM−1 cm−2) and a low detection limit (0.03256 µM). The created electrode offers a viable way to quickly and precisely identify BPA in a variety of samples, supporting initiatives related to health, safety, and the environment.
