根据两阶段吸附模型,导出了两常数及一常数吸附等温线公式。不仅可以方便地应用于各种类型的表面活性剂在固/液界面上的吸附数据,而且具有预示能力。对于显示LS型等温线的体系只需测定第一平台处和饱和的吸附量即可给出整个的吸附等温线。对于离子型表面活性剂在反电性固体上的吸附,可自一个化合物的吸附预示出一系列同系物在同一吸附剂上的吸附等温线。 According to the two-stage adsorption model, two constant and one constant adsorption isotherms were derived. Not only can it be conveniently applied to the sorption data of various types of surfactants at the solid / liquid interface, but also has predictive power. For systems displaying the LS type isotherms, the entire adsorption isotherm can be given by simply determining the amount of adsorption at the first station and saturation. For the adsorption of ionic surfactants on counter electrostatics, the adsorption isotherm can be predicted from the adsorption of one compound on the same adsorbent for a range of homologues.
