Abstract A new type of three-phase separation phenomenon was found by the charge neutralization of perfluorooctanate ion {PFOA−, CF3(CF2)6-COO−} with amylammonium ion (R-N+H3). For example, a three-phase system was formed at pH = 6.8 and [PFOA]T/[amine]T = 0.5. The partition behaviors of solutes such as water-soluble porphyrin and compounds in vivo into each liquid phase were examined.
