Abstract: A solvent extraction process for removing poly- and perfluoroalkyl substances (PFAS) from a PFAS laden adsorbent is disclosed. The process comprises introducing a substantially pure solvent at an elevated temperature to a bed of the PFAS laden adsorbent and continuously removing PFAS laden solvent from the adsorbent, wherein the introducing and removing are carried out simultaneously and continuously until a desired amount of PFAS is removed from the adsorbent. Also disclosed is a process for degrading poly- and perfluoroalkyl substances (PFAS) to environmentally benign products. The process comprises providing an aqueous solution containing PFAS at a concentration of greater than 50 ppm; and subjecting the aqueous solution to ultrasound using at least one ultrasonic transducer at a frequency and power and for a time sufficient to degrade substantially all of the PFAS in the solution to carbon dioxide and fluoride.

Abstract: An adsorbent having a microwave absorption property is provided. The adsorbent having an improved microwave absorption property, which has a core-shell structure including a silicon carbide bead disposed therein, and an adsorbing material disposed outside the silicon carbide bead, can be provided. Also, the adsorbent may further include a plurality of silicon carbide particles dispersed and disposed therein and having a diameter of 1 μm to 10 μm, and the adsorbing material may be ion-exchanged with a cation. Therefore, the adsorbent can be useful in improving desorption efficiency since the adsorbent may be rapidly heated by microwaves to reach the desorption temperature due to high reactivity to microwaves. Also, the adsorbent can be useful in maintaining full adsorption capacity without having an influence on adsorption quantity since the silicon carbide bead is disposed in the inner core of the adsorbent. Further, when the adsorbent is applied to conventional systems for removing organic compounds using microwaves or dehumidification systems, the adsorbent can be semi-permanently used, and may also have an effect of enhancing the energy efficiency by 30% or more, compared to adsorbents used in the conventional systems.
