摘要:
以芘为荧光探针,十六烷基氯化吡啶为猝灭剂,用芘饱和水溶液配制浓度范围为0.10 ~2.40 mmol/L的系列Gemini阳离子表面活性剂溶液,用稳态荧光探针法测定了该系列表面活性剂的临界胶束浓度CMC与胶束聚集数Nm.实验结果表明:该方法测定的CMC值与电导率法测定的CMC值相当; 选择猝灭剂浓度为0.20~0.50 mmol/L时,所测得的表面活性剂胶束聚集数基本不变; 当表面活性剂16-X-16浓度为4~9倍CMC时,胶束聚集数随表面活性剂浓度增大而线性增大; 利用外推法得到的该表面活性剂临界胶束聚集数约为亲油基同碳数的CTAB临界胶束聚集数的一半.
Abstract:
The critical micelle concentration(CMC)and micellar aggregation numbers of series of cationic Gemini surfactants are determined by steady-state fluorescence probe method in which pyrene was used as a fluorescence probe and cetylpyridinium chloride as a quencher. The experimental results indicate that the CMC values are basically in agreement with the values determined by conductivity method, the aggregation numbers of this series cationic Gemini surfactants are essentially constant when the concentrations of the quencher are in 0.20 to 0.50 mmol/L. The aggregation numbers of the Gemini surfactant(16-X-16)increases linearly with the increase of surfactant concentration in the range of 4 to 9 times of CMC. The critical micellar aggregation numbers obtained by extrapolation method are half of the CTAB’s(cetyltrimethylammonium bromide)which is hydrophobic with the same carbon number.
