摘要
Both critical micelle concentration(CMC)and the counter-ion association degree (K) of aqueous cationic surfactants solutions (DTMAC,DTAC,TTAC,CTAC,OTAC)could be determined simultaneously by chloride ISE.The experimental results showed that the CMC were in agreement with the literature value.ISE was both simple and quick,and the results were accurate,reliable and satisfied.The reasons for the differences between the results obtained from both ISE and conductance methods were also discussed in detail in this paper.
