Magnetic adsorbents are widely used in environmental remediation for the removal of pollutants from water, such as heavy metals, dyes, and organic contaminants. Their magnetic properties allow for easy separation from the treated water using an external magnetic field, making the process efficient and cost-effective. In the field of biomedicine, they are utilized for drug delivery systems, where they can be guided to specific target sites in the body using magnetic fields. Additionally, magnetic adsorbents play a crucial role in the purification of proteins and enzymes, aiding in biotechnological and pharmaceutical research. They are also employed in catalysis, where they facilitate chemical reactions and can be easily recovered for reuse.
