摘　　要：以芘作为荧光探针,十六烷基氯化吡啶(CPC)作为猝灭剂,根据芘的荧光强度之比随表面活性剂水溶液浓度的变化,测定十二烷基硫酸钠(SDS)的临界胶束浓度(cmc),测定值与文献值较一致。并用外推法得到SDS的胶束聚集数(n)。文章提供了一种简单可行的实验方法了来计算和评价胶束的基本特性。The critical micelle concentration and the micelle aggregation number of sodium dodecyl sulphate ,were determined by pyrene as fluorensence probe and CPC as quencher, in comparison to the reference, concentration was investigated by steady state fluorescence probe and compared with the reference. The critical aggregation number N can be extrapolateed from N-c curve. The properties of micelles can be evaluated simply by the method.
