表面活性剂水溶液的电导率研究方法和一些特征数据的提取

Conductivity for the Investigation of Ionic Surfactants in an Aqueous Solution and Some Characteristic Parameters

电导率是研究水溶液中离子型表面活性剂胶束化行为的重要方法,本文总结了这个灵敏测定技术,分别着重讨论了两个重要特征参数(临界胶束浓度(cmc)和胶束的反离子解离度(α))的提取方法、电导率曲线某些特殊情况的分析以及预胶束化行为的研究,这对运用电导率技术研究当前不断增多的具有强分子间相互作用的表面活性剂(例如Geminis)体系具有参考价值.

Conductivity is important in the investigation of the micellization behavior of ionic surfactants in an aqueous solution.We review this sensitive technique and discuss methods to determine the critical micelle concentration（cmc） and the degree of dissociation of the micelle（α） in detail.We also investigate a special situation analysis for conductivity curves and premicellar behavior.This method is useful for the investigation of surfactant systems in which strong intermolecular interactions occur.
