Perfluorodecanoic

The physical meaning of the g" (ion) potential depends on the accepted model of ionic double layer. The proposed models correspond to the Gouy Chapman diffuse layer, with or without allowance for the Stern modification and/or the penetration of small counterions above the plane of the ionic heads of the adsorbed large ions [17,18]. The presence of adsorbed Langmuir monolayers may induce very high changes of the surface potential of water. For example. A/" shifts attaining ca. —0.9 (hexadecylamine hydrochloride), and ca. -bl.OV (perfluorodecanoic acid) have been observed [68].

An aqueous solution of potassium perfluorodecanoate was prepared by dissolving 0.016 gram of the free acid into 10 ml. of distilled water and exactly neutralizing with aqueous potassium hydroxide. The resulting solution was diluted with distilled water to a concentration of 3x10 mole per liter of the potassium salt.

PFOA, Fig. 7.1) has been the most commonly used, but chain lengths of C9 (perfluorononanoic acid— PFNA), CIO (perfluorodecanoic acid—PFDA), and longer have also been utihzed. Although PFCAs can be produced in separate chain lengths, most commercial products consist of mixtures of several chain lengths.
