Application of Fe and Cu nanoparticles for methyl orange removal from water and water-ethanol mixtures under various experimental conditions
In this study, metallic iron nanoparticles (Fe NPs) and metallic copper nanoparticles (Cu NPs) were prepared, characterized, and used in the removal of methyl orange (MO) dye. The experiments investigated first the UV–Vis spectra of dye molecules in three types of solvents (water, water-ethanol, and water-dimethyl sulfoxide). The removal of MO was then conducted under various experimental conditions to investigate the effects of solvent type, nanoparticles dosage, salinity of the solutions, temperature, and shaking time. The highest extent of MO removal was achieved in water solutions. Under all experimental conditions, Fe NPs showed higher efficiency than Cu NPs in MO removal. Moreover, heterogeneous Fenton process led to smaller MO removal when compared with the direct use of the nanoparticles, for both water and water-ethanol solutions. From a kinetic perspective, the dye removal process was much faster in water than in water-ethanol mixtures, and the data followed pseudo-second order rate equation.
期刊介绍：
Water Resources and Industry moves research to innovation by focusing on the role industry plays in the exploitation, management and treatment of water resources. Different industries use radically different water resources in their production processes, while they produce, treat and dispose a wide variety of wastewater qualities. Depending on the geographical location of the facilities, the impact on the local resources will vary, pre-empting the applicability of one single approach. The aims and scope of the journal include: -Industrial water footprint assessment - an evaluation of tools and methodologies -What constitutes good corporate governance and policy and how to evaluate water-related risk -What constitutes good stakeholder collaboration and engagement -New technologies enabling companies to better manage water resources -Integration of water and energy and of water treatment and production processes in industry
