Magnetic adsorbents are widely used in environmental remediation for the efficient removal of pollutants such as heavy metals, dyes, and organic compounds from water. Their magnetic properties allow for easy separation from the treated solution using an external magnetic field, simplifying the cleanup process. In the field of biotechnology, they are employed for the separation and purification of biomolecules like proteins, DNA, and cells, enhancing the efficiency of diagnostic and research applications. Additionally, magnetic adsorbents are utilized in catalysis, where they serve as a support material for catalysts, enabling easy recovery and reuse. Their versatility and effectiveness make them valuable in various industrial and scientific processes.
