在 pH >2的水溶液中 ,石英表面带负电荷。当以Ca2 + 作为吸附桥时 ,阴离子表面活性剂能够吸附在石英表面上 ,以液隔电极式压电传感器实时监测该吸附过程中的质量变化 ,获得吸附动力学参数。
In pH> 2 aqueous solution, the quartz surface is negatively charged. When Ca2 + is used as the adsorption bridge, the anionic surfactant can adsorb on the quartz surface, and the mass change during the adsorption process can be monitored by the liquid-crystal piezoelectric sensor in real time to obtain the adsorption kinetic parameters.
