(118b) Magnetic Nanocomposites for Environmental Remediation

Magnetic nanocomposites can provide unique solutions to environmental problems. The magnetic nanoparticles embedded in nanocomposite enable energy to be delivered remotely to the material using an alternating magnetic field (AMF). This localized energy can be used to drive processes to enhance material performance, including disruption of binding interactions, increased reactivity etc. Here, we will highlight a few diverse applications (e.g., sorb/desorb contaminant, activating radical, degrading contaminant). For example, decades of use of halogenated chemicals in product manufacturing and commercial applications have been connected to detrimental health impacts. In response to these, we have applied magnetic nanocomposite for the sorption of contaminants such as perfluoroalkyl substances (PFAS) and desorption through an AMF.
