摘　　要：对不同类型表面活性剂(阳离子型、阴离子型、非离子型、正负混合型)在短碳链醇/水混合溶剂中的表面物化性质进行了较为系统的研究,探讨了短碳链醇加入对体系γcmc值和cmc值的影响.发现各类体系的γcmc随短碳链醇加入的变化规律并非决定于表面活性剂类型而取决于该表面活性剂在水溶液中的饱和吸附量和cmc值的大小.The surface chemical properties of various kinds of surfactants (including cations, anionic, nonionic and cationic surfactants) in mixed fatty alcohol/water solvents were investigated. In different surfactant systems, short fatty alcohol content influences the gamma (cmc) differently. It is found that the varying tendency of gamma (cmc) induced by short fatty alcohol addition can be predicted from their saturation adsorption and gamma (cmc) values in water, rather than the types of surfactants.
