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 and recovery from the treated water using an external magnetic field, eliminating the need for complex filtration processes. In the biomedical field, they are employed for targeted drug delivery, where the adsorbent can be guided to specific sites in the body using magnetic fields, enhancing treatment precision. Additionally, they are utilized in protein purification and enzyme immobilization, where their high surface area and magnetic responsiveness streamline separation processes. In analytical chemistry, magnetic adsorbents serve as effective tools for sample preparation, enabling the extraction and concentration of analytes from complex matrices. Their versatility and ease of use make them valuable in various industrial and scientific applications.
