综述了质子核磁共振的几种方法在表面活性剂水溶液研究中的应用.自从上世纪六十年代以来的许多研究表明核磁共振的各种技术是研究表面活性剂溶液的有效手段.它可以提供表面活性剂在水溶液中的cmc、胶束的结构、尺寸、水化、加溶性质和位置,不同表面活性剂胶束之间的相互作用,以及胶束与生物分子和高聚物的相互作用.化学位移已经成为惯常方法,弛豫测量提供动态信息,自扩散系数测量是研究胶束尺寸的很好手段.近来由于核磁共振技术的不断发展,用于研究生物大分子的2DNOESY和HOESY也逐渐应用到研究表面活性剂聚集结构中.由此可以得到有关表面活性剂在水溶液中行为的分子水平信息,是其它谱学方法所不能及的.
Several methods of proton nuclear magnetic resonance are reviewed in the application of surfactant aqueous solutions.Many studies since the 1960s have shown that NMR techniques are an effective means of studying surfactant solutions and can provide surface Cmc of the active agent in aqueous solution, the structure, size, hydration, solubility and location of the micelles, the interaction between the different surfactant micelles, and the interaction of the micelles with the biomolecules and polymers. Chemical shifts have become the norm, relaxation measurements provide dynamic information, and self-diffusion coefficient measurements are a good means to study micelle size. Recently, due to the continuous development of nuclear magnetic resonance technology, 2DNOESY and HOESY for the study of biological macromolecules have also been gradually applied To study the aggregate structure of the surfactant, thus obtaining molecular level information on the behavior of the surfactant in aqueous solution that is beyond the reach of other spectroscopic methods.
