Mining in Ecuador is mostly made up of small-scale or artisanal mining, causing serious environmental problems due to the high content of heavy metals discharged by its effluents in the country's main mining areas. On the other hand, it is known that iron and iron sulfide nanoparticles present high adsorption of different pollutants. In this research, the action of multi-component nanoparticles (NPsMC) in metal-contaminated soils was studied. To this end, chemical synthesis was carried out and characterization was performed using microscopic and analytical techniques SEM, TEM, EDS and XRD. The...
