| Abstract: | The surface tension isotherms of ammonium perfluorooctanoate, ammonium perfluo-rononanoate and their mixed aqueous solutions with ammonium chloride (0. 1 mol/L) have been measured by using drop volume method at 25℃. The micellization, adsorption and surface tension reduction in these systems are discussed. Anew method for calculating the whole γ-lgC curves of the ideal solutions of the mixtures was developed and good correspondence between the calculated and experimental results was obtained. |
