| 摘 要： | 本文测定了阳离子表面活性剂 CTAB(溴化十六烷基三甲基铵)水溶液在石英和甲基化石英表面的接触角、(?)电位及吸附等温线。讨论了在酸性溶液(PH=4.5)和碱性溶液(PH=8.5)情况下 CTAB 的吸附机理。研究结果表明:甲基化和非甲基化表面吸附机理的差别;甲基化表面在水溶液中长时间浸泡其表面由憎水向亲水方向转移是在作表面性能研究时必须严重关注的问题。

| Abstract: | Contact angle,Zeta potential and adsorption isotherm for CTAB(cetyl trimethyl am- monium bromide)on Quartz and methylated Quartz and methylated Quartz have been de- termined.The schematic adsorption mechanism at PH4.5 and 8.5 are predicted.It is shown that the adsorption mechanism is different for Quartz and methylated Quartz.The contact time has great effect on surface property of the methylated Quartz.This behaviour is relevant to the hydrophobic-hydrophilic transition on surface of the methylated Quartz. |
