| Abstract: | Equilibrium surface tension and adsorption dynamic characteristics of perfluoroalkyl quaternary ammonium iodide (Le-134), perfluoroalkyl phosphate (Le-107) and perfluoroalkyl polyether (Le-180) were investigated. The relationship between the critical micelle concentration is Le-180 (15×10-6) -6) -6); the saturation adsorption amount Γmax is Le- 107 Da) and adsorption barriers (Ea) of three aqueous surfactant solutions at different concentrations were investigated. It can be indicated that the variation of adsorption dynamics is mainly due to the difference in molecular structure and the influence of micelles on adsorption process. |
