固体自溶液中的吸附是胶体与界面化学最古老的研究课题之一,也是应用最多最广泛的一个领域。但因涉及的体系和问题极其复杂,理论上的进展十分困难。近二三十年来,随着表面活性剂工业的兴起,表面活性剂的应用也越来越普遍。这类应用的成败往往取决于表面活性剂在界面上的吸附。大量实践表明,不同类型或不同品种的表面活性剂混配(如非离子型-阴离子型、非离子型-阳离子型、阴离子型-阳离子型、两种不同的非离子型表面活性剂等等),往往有更好的效果。但工业用表面活性剂几乎无例外地都是混合物(例如链长不同的同系混合物),而不是纯品。因此,表面活性剂混合物在界面上的混合吸附是一个
Solid adsorption from the solution is one of the oldest research topics in colloid and interfacial chemistry and one of the most widely used fields. However, due to the extremely complicated systems and issues involved, theoretical progress has been very difficult. In the past 20 to 30 years, with the rise of the surfactant industry, the application of surfactants has become more and more common. The success or failure of such applications often depends on the surfactant adsorption at the interface. Extensive practice has shown that the blending of surfactants of different types or varieties (eg nonionic - anionic, nonionic - cationic, anionic - cationic, two different nonionic surfactants, etc.) , Often have better results. Industrial surfactants, however, are almost invariably mixtures (for example homologues with different chain lengths), rather than pure products. Therefore, the mixture of surfactants in the interface of mixed adsorption is one
