Title
(EN) PERFLUOROALKYL AND POLYFLUOROALKYL SORBENT MATERIALS AND METHODS OF USE
(FR) MATÉRIAUX SORBANTS DES PERFLUOROALKYLES ET DES POLYFLUOROALKYLES ET PROCÉDÉS D'UTILISATION
Abstract
(EN)
Sorbent materials that are treated with ions, salts, oxides, hydroxides, or carbonates of calcium, magnesium, strontium, or barium are useful in removing perfluoroalkyl and polyfluoroalkyl substances (PFAS), perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), 2,3,3,3,-tetrafluoro-2-(heptafluoropropoxy)propanoate and heptafluoropropyl 1,2,2,2-tetrafluoroethyl ether, and similar compounds from liquids and gases are disclosed. The sorbent materials with the disclosed treatments offer improved performance as measured against untreated sorbent materials.
(FR)
Cette invention concerne des matériaux sorbants qui sont traités avec des ions, des sels, des oxydes, des hydroxydes ou des carbonates de calcium, de magnésium, de strontium ou de baryum et qui sont utiles pour l'élimination des substances perfluoroalkylées et polyfluoroalkylées (PFAS), de l'acide perfluorooctanoïque (PFOA), de l'acide perfluorooctanesulfonique (PFOS), du 2,3,3,3,-tétrafluoro-2-(heptafluoropropoxy) propanoate et de l'heptafluoropropyle 1,2,2,2-tétrafluoroéthyléther, et des composés similaires à partir de liquides et de gaz. Les matériaux sorbants avec les traitements décrits offrent des performances améliorées telles que mesurées par rapport à des matériaux sorbants non traités.
