Magnetic adsorbents are widely used in environmental remediation for the efficient removal of pollutants such as heavy metals, dyes, and organic contaminants from water. Their magnetic properties allow for easy separation from the treated water using an external magnetic field, eliminating the need for filtration or centrifugation. In the biomedical field, they are employed for targeted drug delivery, where the adsorbents can be guided to specific sites in the body using magnetic fields, enhancing therapeutic efficacy. Additionally, they are utilized in bioseparation processes to isolate biomolecules like proteins, DNA, and cells from complex mixtures. In industrial applications, magnetic adsorbents are used for catalyst recovery, enabling the reuse of expensive catalysts and reducing waste. Their versatility and ease of separation make them valuable in various scientific and industrial processes.
