表面活性剂溶液的动表面张力研究

Studies on Dynamic Surface Tension of the Aqueous Surfactant Solutions

用振荡射流法分别测定了不同温度下全氟辛酸、十二烷基硫酸钠、二聚氯乙烯正辛醇醚溶液(浓度低于CMC)的动表面张力,讨论了它们的表面吸附动力学,研究结果表明都是扩散控制。

The dynamic surface tensions of the aqueous solutions of per-fluorooctanoic acid, sodium dodecylsulfate and diethylene glycol mono-w-octyl ether were measured at different temperatures by the oscillating jet method, respectively. The results show that the surface adsorption of all these systems is diffusion-controlled.
