Cleansing Water: Harnessing Trimetallic Nanoparticles in Sunlight to Degrade Methylene Blue Dye, Aiding Aquatic Contaminant Cleanup

Water, Journal Year: 2023, Volume and Issue: 15(19), P. 3404 - 3404

Published: Sept. 28, 2023

The contamination of industrial water sources with synthetic dyes, such as methylene blue (MB), remains a persistent environmental concern, demanding effective remediation techniques. In response, this research centers on the utilization trimetallic nanoparticles (TMNPs) composed Fe-Ni-Cr, Fe-Ni-Cd and Fe-Ni-Cu promising solution to address color-related pollution in aquatic ecosystems. These were synthesized using wet chemical precipitation method rigorously characterized Fourier transform infrared (FT-IR), energy-dispersive X-rays (EDX), scanning electron microscopy (SEM). Armed these nanoparticles, our primary objective was harness their photocatalytic prowess when exposed direct sunlight aqueous environments for degradation MB. progress photodegradation meticulously monitored reliable visible spectrophotometer, providing insights into kinetics. Remarkably, within just six hours solar irradiation, TMNPs exhibited remarkable capacity degrade MB, achieving an impressive rate ranging from 77.5% 79.4%. relentless pursuit optimization, we conducted comprehensive examination various parameters including catalyst dosage, dye pH levels, focusing specifically Fe-Ni-Cr TMNPs.
