摘要
利用压电传感器实时监测聚乙烯醇(PVA)在石英表面的吸附过程,结果表明该吸附过程的动力学符合一级动力学模型,其吸附等温线符合Langmuir模型,随着溶液pH升高,吸附平衡常数与饱和吸附量下降.
The adsorption process of polyvinyl alcohol on quartz surface was monitored in real time by a piezoelectric sensors. It was shown that the adsorption kinetics followed the pseudo-first-order kinetic model and the adsorption isotherm obeyed the Langmuir isotherm model. With increasing pH, the adsorption equilibrium constant and saturation amount adsorbed were decreased.
