Abstract

The adsorption of dodecyl, tetradecyl, hexadecyl, and octadecyl trimethylammonium chlorides at an interface between porous glass and potassium chloride solution has been characterized by measurements of membrane potentials. The specific potential Φ is 0.97 kT per methylene group (where k is the Boltzmann constant and T is the absolute temperature) or 580 calories per mole at 23°C.
