Magnetic adsorbents are widely used in environmental remediation for the efficient removal of pollutants such as heavy metals, dyes, and organic contaminants from wastewater. 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 pharmaceutical industry, they are employed for the purification of drugs and the extraction of bioactive compounds from complex mixtures. Additionally, magnetic adsorbents play a significant role in biotechnology for the isolation and purification of biomolecules like proteins, DNA, and enzymes. Their high surface area and tunable surface chemistry make them effective in catalysis, where they facilitate reactions and can be easily recovered for reuse. In analytical chemistry, they are utilized for sample preparation, enabling the preconcentration of target analytes for more accurate detection and analysis.
