界面振荡现象
摘要:
表面活性剂十二烷基三甲基溴化铵从水相向硝基乙烷相的迁移导致以界面振荡为特征的界面不稳定现象．基于界面吸附平衡对该现象的成因进行解析，得到了体现溶质界面吸附和扩散迁移的双因素关系式，可对界面振荡运动的成因及有关规律作出解释．

Interfacial Oscillation Phenomenon
Abstract:
An interfacial oscillation phenomenon in the system of dodecyltrimethylammonium bromide, water and nitroethane, induced by the solutal Maran ni 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 Maran ni effect, which is the composite result of the solutal interfacial adsorption and the difference of the solute diffusion in the two phases.
