Ammonium perfluorooctanoate--also called APFO, PFOA or C8--is a surfactant
associated with the production of Teflon.RTM., and is also present in
products such as fire-fighting foams and may be formed from the microbial
degradation of grease-resistant coatings applied to items such as pizza
boxes. APFO itself does not hydrolyze, photolyze, or biodegrade under
environmental conditions and is biologically additive. A process by which
APFO may be removed and recovered from water by electrosorption is
discovered. Removal and recovery by electrosorption form an inexpensive
and environmentally friendly method of removal and recovery of APFO.
