Abstract

Le problème technique Fournir un procédé pour éliminer sélectivement un acide organique contenant du fluor ayant 2-7 atomes de carbone, avec une faible énergie et en une courte durée Moyen pour résoudre le problème Procédé pour séparer un acide perfluorohexanoïque dans une solution de l'acide organique contenant du fluor ayant 2-7 atomes de carbone par osmose inverse avec une membrane semi-perméable, où la membrane semi-perméable a une masse moléculaire de coupure supérieure à la masse moléculaire de l'acide organique contenant du fluor ayant 2-7 atomes de carbone et a un potentiel zêta de surface négatifThe technical problem Provide a method for selectively removing an organic acid containing fluorine having 2-7 carbon atoms, with low energy and in a short time Means to solve the problem Method for separating a perfluorohexanoic acid in an acid solution fluorine-containing organic having 2-7 carbon atoms by reverse osmosis with a semipermeable membrane, where the semipermeable membrane has a molecular weight cut-off greater than the molecular weight of the fluorine-containing organic acid having 2-7 carbon atoms and has a negative surface zeta potential
