重点讨论了表面活性剂的单体或预胶束溶液中气/液界面的平衡与动态的表面张力和吸附情况。平衡表面张力的数据可联系到Langm uir平衡吸附等温方程和Gibbs吸附方程;介绍了动态表面张力测量方法与基本参数,讨论了扩散控制吸附模型与混合动力吸附模型;由动态表面张力数据可得到表观扩散系数值,并结合吸附模型中,可得到动态吸附的各个参数(如吸附速率常数、脱附速率常数等)。同时,对表面活性剂胶束溶液的动态表面张力与吸附动力学也作了初步的论述。
The equilibrium and dynamic surface tension and adsorption of the gas / liquid interface in surfactant or pre-micellar solution are discussed. The data of the equilibrium surface tension can be linked to the Langmuir equilibrium adsorption isotherm equation and the Gibbs adsorption equation. The dynamic surface tension measurement method and basic parameters are discussed. The diffusion controlled adsorption model and the hybrid adsorption model are discussed. The dynamic surface tension data View of diffusion coefficient values, combined with the adsorption model, the dynamic adsorption of various parameters (such as adsorption rate constant, desorption rate constant, etc.). At the same time, the dynamic surface tension of surfactant micellar solution and adsorption kinetics are also discussed.
