Abstract
Methods, systems and apparatuses for the capture, desorption and/or destruction of pollutants such as PFAS. The systems include porous polymer materials such as foams like polyurethane and may include nanoparticles and/or active chemical groups. The porous polymer may be activated to improve capture. Captured pollutants may be desorbed using solvents and mechanical methods, and the pollutants may then be concentrated and destroyed through the application of energy such as through acoustic energy, ultrasound, and/or light such as UV or visible light.
