| 摘 要： | 将碳酸钙颗粒分散于聚苯乙烯溶液中，并在石英晶体微天平（QCM）表面成膜，以稀盐酸将膜中的碳酸钙颗粒溶解，获得多孔的聚苯乙烯薄膜，以QCM动态传感监测表面活性剂在多孔膜上的吸附过程．结果表明，十二烷基苯磺酸钠、氯代十六烷基吡啶、TX-114均在聚苯乙烯薄膜上吸附，三种表面活性剂在多孔膜上的吸附动力学和等温线可以分别用Langmuir动力学和等温线模型回归分析，得到了有关吸附动力学参数和吸附等温线参数．

| Abstract: | Calcium carbonate particles were dispersed in polystyrene solution.A thin film of polystyrene with CaCO_3 particles was fabricated on the surface of a quartz crystal microbalance(QCM).A porous polystyrene film was obtained by decomposing CaCO_3 particles with diluent hydrochloric acid.The absorption processes of surfactants,including sodium dodecyl benzenesulfonate,cetylpyridinium chloride and TX-114,onto the porous polystyrene film were monitored in real time by the QCM.The experimental results indicated t... |
