Magnetic adsorbents are widely used in environmental remediation for the efficient removal of pollutants from water. They are particularly effective in adsorbing heavy metals, dyes, and organic contaminants due to their high surface area and magnetic properties, which allow for easy separation from the treated water using an external magnetic field. In wastewater treatment, these adsorbents offer a sustainable and cost-effective solution for purifying industrial effluents. Additionally, they are employed in the extraction and recovery of valuable metals from mining waste or electronic scrap. In biotechnology, magnetic adsorbents are utilized for the separation and purification of biomolecules, such as proteins and DNA, enabling advanced research and diagnostic applications. Their versatility and efficiency make them a valuable tool in both industrial and scientific fields.
