摘　　要：利用动态表面张力研究方法,对不同质量比的烷基苯磺酸胺盐和椰子油二乙醇酰胺进了行研究,并利用2种数学模型对动态吸附数据进行分析,结果表明将吸附过程分成不同时区的数学模型能更好的体现表面活性剂的动态吸附过程,为表面活性剂在实际应用中的表现提供预测和参考。With the dynamic surface tension data,the surfactant system of ammonium lauryl sulfate and coco diethanolamide at different mixture ratios was studied, using mathematical models the dynamic adsorption profile of surfactant system was analyzed.The study indicated that the mathematical model which divided the dynamic adsorption process into different time regime can fit in each individual time regime better. Therefore, the model we set up for dynamic adsorption of surfactant system can correlate much better with the surfactant performance in real application, and can provide better prediction and reference.
