Recent progresses of magnetically-controlled adsorption materials in the detection of environmental pollutants

Environmental pollutants, such as heavy metals, textile dyes, and emerging contaminants, pose significant risks to ecosystems and human health, necessitating the development of effective detection and remediation strategies. Traditional methods often lack sensitivity, stability, and operational efficiency. This review highlights recent advancements in magnetically-controlled adsorption materials, including magnetic carbon materials, magnetic metal-organic frameworks (MOFs), and magnetic composites. These materials leverage magnetic responsiveness and advanced adsorption capabilities for efficient separation and high selectivity, even at trace concentrations. Key aspects, including synthesis strategies, structural features, and application in pollutant adsorption, are comprehensively examined. While challenges such as scalability and long-term stability persist, emerging innovations in green synthesis, functionalization, and hybrid material development offer promising solutions. By combining advanced functionalities with sustainable practices, magnetically-controlled adsorption materials present transformative potential for environmental monitoring and remediation, paving the way for sustainable pollutant management.
