Название (рус.): | Вещества поверхностно-активные катионные (хлоргидраты и бромгидраты). Определение критической концентрации образования мицелл. Метод измерения активности противоионов |
Название (англ.): | Cationic surface active agents (Hydrochlorides and hydrobromides); Determination of critical micellization concentration; Method by measurement of counter ion activity |
Описание (англ.): | 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. |
