二元表面活性剂复配体系相互作用的研究

THE STUDY OF THE LNTERACTION IN BINARY MIXED SYSTEM OF SURFACTANTS

本文对非离子表面活性剂聚氧乙烯(n=23)月桂基醚(Brij—35)和阴离子表面活性剂十二烷基硫酸钠(SDS)及阳离子表面活性剂十六烷基三甲基溴化铵(CTAB)为二元表面活性剂复配水溶液体系,在气—液界面和胶团中的有关物化性能进行了一系列测试,对它们之间的相互作用机理进行了探讨,得出了分子间相互作用参数β_s和β_m,并对复配体系相互作用增效情况进行了讨论。

The physicochemical properties of aqeous solution ofbinary surfactants system are studied when Nonionic surfactaht pol-yoxyethylene (n=23) lauryl ether (Brij-35) is mixed with cati-onic surfactant hexadecyltrimethylammonium bromide (CTAB) andanionic surfadant sodium dodecanesulfulate (SDS) separately. Aseries of parameters of interaction at the gas/liquid interfaces (β_s)and in micelle (β_m) are obtained, and the interaction mechanismof these systems are investigated. The synergism of these mixedsystems are discussed.
