标准摘要
[中文适用范围]： 测定如下进行：电位测定一系列浓度覆盖预期胶束化浓度的阳离子表面活性剂溶液的氯离子或溴离子活性。 绘制电位与浓度对数函数的关系图； cmc 对应于该曲线上的奇点。 该方法适用于纯化的阳离子表面活性剂(盐酸盐和/或氢溴酸盐)，其可溶于水且克拉夫特温度低于60摄氏度。 [外文原描述]： The determination is carried out as follows: Potentiometric determination of the chloride or bromide ion activity of a series of solutions of cationic surface active agents the concentration of which cover the expected micellization concentration. Plotting the graph of potential as a function of the logarithm of the concentration; the c.m.c. corresponds to the singularity on this curve. The method is applicable to purified cationic surface active agents (hydrochlorides and/or hydrobromides), which are soluble in water and which have a Krafft temperature below 60 degree Celsius.
英文名称Cationic surface active agents (Hydrochlorides and hydrobromides) — Determination of critical micellization concentration — Method by measurement of counter ion activity
