Title: Studies on the Aqueous Solutions of Guanidinium Salts. XIV. Effect of Guanidinium Bromide on the Surface Tension of Aqueous Solutions of the Cationic Surfactants
Abstract: The surface tensions of decyl-, tetradecyl-, and hexadecyl-trimethylammonium bromides were measured in the aqueous solutions of potassium bromide (KBr) and guanidinium bromide (GuBr). The critical micelle concentrations (CMC’s) of the above surfactants decreased with increase of the concentration of KBr, while the CMC’s showed minimum values in the aqueous GuBr solution, as the concentration of GuBr increased. The Langmuir coefficient, KC, increased with decrease of the CMC. The influence of the salts on the surface tension and the micellization were well described in terms of the activity of the surfactant calculated by combining the Debye-Hückel law and Setschenow’s equation.
