Title
(EN) REUSABLE FUNCTIONALIZED HYDROGEL SORBENTS FOR REMOVING PERFLUOROALKYL AND POLYFLUOROALKYL SUBSTANCES FROM AQUEOUS SOLUTION
(FR) SORBANTS D’HYDROGEL FONCTIONNALISÉS RÉUTILISABLES POUR ÉLIMINER DES SUBSTANCES PERFLUOROALKYLE ET POLYFLUOROALKYLE D’UNE SOLUTION AQUEUSE
Abstract
(EN)
Hydrogel-based sorbents and methods for their use in collecting, concentrating, and removing environmental per- and poly-fluoroalkyl substances. In one aspect, the invention provides hydrogel-based sorbents that are effective for collecting, concentrating, and removing PFASs from an environment in which the sorbent is placed; an environment in which the sorbent is in contact with (e.g., liquid communication).
(FR)
La présente invention concerne des sorbants à base d’hydrogel et des procédés pour leur utilisation dans la collecte, la concentration et l’élimination de substances perfluoroalkyle et polyfluoroalkyle dans l’environnement. Dans un aspect, l’invention concerne des sorbants à base d’hydrogel qui sont efficaces pour collecter, concentrer et éliminer des PFA d’un environnement dans lequel le sorbant est placé ; un environnement avec lequel le sorbant est en contact (par exemple, en communication liquide).
