Magnetic adsorbents are widely used in environmental remediation for the removal of contaminants from water, such as heavy metals, dyes, and organic pollutants. Their magnetic properties allow for easy separation from the treated water using an external magnetic field, making the process efficient and cost-effective. In industrial applications, they are employed for wastewater treatment, helping to recover valuable metals and reduce pollution. Additionally, magnetic adsorbents are utilized in biomedical fields for targeted drug delivery, where they can be guided to specific sites in the body using magnetic fields. They also play a role in protein purification and separation processes in biotechnology, offering a fast and scalable solution for isolating biomolecules.
