Determination was made of critical micelle concentrations (cmc) for three ho-mologs of perfluoroalkanesulfonate salts, CnF2n+1SO3Li (n=4, 6, 8, 10), CnF2n+1SO3Me4N (n=4, 6, 8, 10), and CnF2n+1SO3Et4N (n=4, 6, 8) in aqueous solutions at 25°C, and the results are expressed in the form, log cmc=A+Bn. B values are -0.435-0.465, indicating cmc to decrease by 2.72.9 for each CF2 group added to perfluoroalkyl chain. Due to the high Krafft points of sodium and potassium salts, the influence of counterions on cmc for C6H13SO3-M+ (M=Li, Na, K, Me4N, and Et4N) was examined at 65°C. It was found that cmc decreased in the order of Li> Na> K> Me4N> Et4N, and this order is discussed on the basis of ionic hydration of alkali metal ions and the hydrophobic interactions of quaternary ammonium ions with micelles.
