摘要
在液隔电极式压电传感器表面修饰聚氯乙烯(PVC)膜,实时监测十二烷基苯磺酸钠在修饰膜表面吸附过程中的质量变化,获得吸附/脱附速率常数、平衡常数、饱和吸附量等参数,并讨论盐浓度的影响。
Polyvinyl chloride(PVC) film is added on quartz surface of an electrode-separated piezoelectric sensor.The adsorption mass of sodium dodecyl benzenesulfonate on PVC surface is monitored real time.The rate constants for adsorption and desorption,equilibrium constant of adsorption and saturation adsorbed mass are obtained.The influence of salt concentration is tested.
