A novel electrochemical sensor. based on a Rh2O3⁻reduced graphene oxide (rGO) composite modified carbon electrode. has been developed for detecting bisphenol A (BPA) in beverages. The prepared Rh2O3/rGO and its precursor materials were characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD). https://chefesquipmenters.shop/product-category/high-chairs/
