摘　　要：本文介绍了离子型表面活性剂在氧化物表面自组装体系的原理及特点。离子型表面活性剂分子从溶液中自发地吸附到氧化物表面形成单分子胶束、双分子胶束和混合胶束,该体系对许多疏水性有机化合物及螯合了有机基团的金属离子具有很强的吸附富集作用。本文根据不同自组装体系的结构分类,详述了它们在分析化学和环境化学中的应用研究,并展望了该技术的应用前景。The theory and characteristics of self-assembled system based on ionic surfactants adsorbed onto oxide surface are introduced. The hemimicelles, admicelles and mixed admicelles are formed by the ionic surfactant molecules adsorbing onto the surface of oxides spontaneously. The formed system has a strong adsorbing function for the hydrophobic organic compounds and metal ions which are chelated with organic reagents. The applications of self-assembled structure in analytical and environmental chemistry are reviewed according to different kinds of self-assembled systems. The future applications are prospected.
