摘　　要：通过荧光光谱法测定了月桂酰单乙醇酰胺硫酸钠(以下简称C12MSN)的胶束聚集数。并分别考察了此表面活性剂浓度、不同添加物醇和无机盐浓度对胶束聚集数的影响。研究发现:胶束聚集数随C12MSN浓度的增大呈线性增大,随醇浓度的增大而减小,随着醇分子烷烃链的增长,这种影响更为显著,随无机盐浓度的增大而明显增大。胶束内核的微极性随表面活性剂浓度和无机盐浓度的增大而减小。Micellar aggregation number of lauric acid monoethanolamine sulfate (hereinafter referred to C12MSN) was determined by fluorescence spectrometry. Also the effects on the aggregation number of micelle were investigated in this surfactant concentration, additives, alcohol and salt concentration. It was found that the concentration of micelle aggregation number increased linearly, the micelle aggregation number decreased with the concentration of alcohol increasing and with the alcohol molecules in alkane chain growth. The impact is more significant, micellar aggregation number increased obviously with the increasing of concentration of salts. Micro-polar micelle core decreased with the increasing of surfactant concentration and salt concentration.
