Using Bismuth Vanadate/Copper Oxide Nanocomposite as Photoelectrochemical Sensor for Naproxen Determination in Sewage

Abstract

Conventional sewage treatment plants are not usually designed to remove emerging contaminants, and this shortcoming leads to the discharge of pharmaceuticals, among other emerging pollutants, into the environment. The present work reports the development of BiVO4/CuO‐based photoelectrochemical sensor for the determination of naproxen in sewage samples. Morphological characterizations were carried out by X‐ray diffraction and Scanning electron microscopy. The band gap energy of the nanocomposite material was ca…
