Abstract
A composition is provided for removal of a target substance from a fluid stream. The composition may be used to remove polyfluorinated alkyl substances (PFAS) from water. The composition comprises a support material comprising an alumina; and a sorbent molecule that comprises a core polymer; wherein the core polymer is covalently linked to the support material; and wherein the sorbent molecule further comprises one or more covalently linked sorbent groups. Processes for removal of target substances such as PFAS are also provided.
