Copper-Modified Iron Oxide Nanoparticles: A Novel Catalyst for Effective Congo Red Dye Degradation in Wastewater Treatment

Abstract

The raising worldwide water tainting from different sources has delivered admittance to unpolluted drinking water progressively testing. The release of effluents containing colors into water bodies become as a basic ecological worry lately. Regular treatment strategies are insufficient in wiping out these steady and risky poisons, requiring the investigation of novel methodologies. In this review, Cu-doped FeO nanoparticles were easily blended by using a co-precipitation strategy, and their synthetic qualities were entirely analyzed. These nanoparticles showed extraordinary adsorption abilities in the corruption of various color compounds. In particular, manufactured acidic color was focused on for expulsion utilizing metal-doped nanoparticles. Ideal boundaries for maximal acidic color not set in stone by surveying the adsorbent portion, beginning color focus, contact time, and temperature. The pH was distinguished as a critical variable, with the best incentive for maximal adsorption of Congo Red Dye viewed as less than 7. As indicated by late discoveries, Cu/FeO nanoparticles displayed unrivalled adsorption limit with regards to Congo Red Dye color at an ideal pH of 2, a measurement of 0.5 g/500 mL, a contact season of an hour and a half, and a color centralization of 150 ppm at 35° centigrade. Pseudo second order adsorption kinetic model exhibited amazing fitting outcomes for adsorption energy and balance information.
