Magnetic nanoparticles can be employed in environmental remediation efforts. Their high surface area and reactive nature make them ideal for removing contaminants from water and soil. For instance, they can be used to remove heavy metals or organic pollutants through adsorption or catalytic degradation. Additionally, once the contaminants are bound, the nanoparticles can be easily separated from the environment using an external magnetic field, making the cleanup process efficient and effective.
