Copper tungstate assisted photocatalytic degradation of Industrial (dye and pharmaceutical) products in water

Abstract

The contamination of ecosystems, specifically water, has emerged as a substantial concern in recent decades. This is mostly owing to the extensive growth of large industries that have provided societal advantages but are also imposing adverse effects on the environment. Azure A (AA) and Azure B (AB) are the cationic dyes commonly employed in industrial, and biomedical fields as intermediates in the production of several pharmaceuticals, as mediators for electrochemical biosensing, and indigo carmine (IC) is an anionic dye used in the textile industry for dyeing. Micropollutants, including the pharmaceutical, propranolol hydrochloride (β-blocker) (PPH) are the pollutants in the subject of discussion. In this research article, CuWO4 catalyst (green catalyst) is used to alleviate the impact of the environment on its ecosystem as a photocatalyst with ultraviolet (UV) irradiation of pollutants (AA, AB, and PPH). For the analysis of pollutants, decomposition, UV-Visible absorption spectroscopy, and High-Pressure Liquid Chromatography (HPLC) are employed. This work demonstrates the promise of nanomaterial-based photocatalysis as a viable and effective method for sustainably tackling water pollution.
