Abstract

A process for removing fluoroorganic anions from an aqueous phase comprises contacting the aqueous phase with an organoammonium, wherein a fluoroorganic anion from the aqueous phase and the organoammonium form a hydrophobic ion pair; and then separating the hydrophobic ion pair from the aqueous phase. The resulting aqueous phase comprises less than 1 % by weight of fluoroorganic anions. The organoammonium may be obtained by protonating an amine in situ. In another aspect, a process for removal of fluoroorganic anions from an aqueous phase comprises contacting the aqueous phase with an organic phase, wherein the organic phase comprises at least one water soluble amine, to form a mixture and agitating the mixture to extract the fluoroorganic anions into the organic phase. The mixture is then allowed to phase separate. Optionally, a base is added to the organic phase to recover the fluoroorganic anions and/or to regenerate the amine.
