摘要
主要讨论了聚氧丙烯 -聚氧乙烯 -聚氧丙烯 (PEP)嵌段共聚醚型非离子表面活性剂分别与十二烷基硫酸钠 (SDS)、十六烷基三甲基溴化铵 (C16TAB)复配体系的水溶液的表面张力随浓度的变化及其盐效应的影响 ,计算了二元复配体系水溶液的表面吸附层分子相互作用参数 ( βσ)及胶束中分子相互作用参数 ( βm)的值 ,比较了复配体系的协同效应 。
Surface tensions of aqueous solutions containing both nonionic surfactant PEP (block copolymer of polyoxypropylene polyoxyethylene polyoxypropylene) and ionic surfactants such as SDS (dodecyl sulfate sodium salt) or C 16 TAB (cetyltrimethyl ammonium bromide) were measured respectively. Effect of added salt on surface tensions was also studied. From the data of the measured surface tensions the interaction parameter β σ( in adsorbed layer) and the interaction parameter β m (in micelles) between nonionic and ionic surfactants were calculated. The synergetic effects of the composite systems were compared each other and some theoretical explanations to these results were given.
