摘要： 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.

摘要： Sorbent material sheets are wound around a center core of material that includes additional sorbent. This configuration further increases the packaging efficiency and performance of the sorbent material sheets as part of an overall housing or apparatus. In some embodiments, the sorbent material sheets are arranged in a stacked configuration. Configurations of the sorbent material sheets as part of a canister are also described.
