【Abstract】 Ah interfacial oscillation phenomenon in the system of dodecyltrimethylammonium bromide, water and nitroethane, induced by the solutal Marangoni effect is observed. A simple model based on the equilibrium of the interfacial adsorption is analyzed, in order to give a detail mechanism of this phenomenon. The result shows that the origin of this interfacial oscillation is the appearance of an interfacial flux induced by the solutal Marangoni effect, which is the composite result of the solutal interfacial adsorption and the difference of the solute diffusion in the two phases.更多还原
