| 摘 要： | 采用荧光光谱法研究了十二烷基苯磺酸钠（SDBS）与非离子表面活性剂TritonX-100混合体系在水溶液中聚集体的性质。 发现在浓度与荧光强度的关系曲线上存在2个转折点，分别对应于混合体系的临界胶团浓度和胶团形状发生转变的浓度。 通过混合胶团相互作用关系，计算了SDBS与TritonX-100的相互作用参数βM，说明SDBS以其自身所带生色基团苯磺酸与TritonX-100发生了协调效应且存在着较强的相互作用。

| Abstract: | Using the chromophore base of benzene sulfonate in sodium dodecyl benzene sulfonate(SDBS), the aggregation property of SDBS with non-ionic surfactant TritonX-100 in aqueous solution was studied by fluorescence. Results show there are two turning points in the variation curve of fluorescence intensity I as a function of concentration, which is the critical micelle concentration and the concentration at which the micelle shape changed, respectively. The interaction parameter βM between SDBS and TritonX-100 was calculated by the formula of mixed micelle interaction. The results show there is synergism and strong interaction between them. |
