The adsorption feature of different kinds of polystyrene-based macroporous adsorption resins (MARs) was investigated systemically at constant temperature employing Rutin as the adsorbate. Different from traditional adsorption patterns, Langmuir and Freundlich adsorption, and the results showed interesting aspects: (1) With the increase of the volume of the initial solution, the adsorption capacity increased to the maximum, and then decreased gradually. (2) Experimental results clearly verified the opinion that the adsorption process of MARs could be divided into three stages-macropores, mesopores, and micropores-by the capillary effects occurring at the two intersections, and the adsorption feature for every stage could be described well by the fourth type of Brunauer model. (3) The model that the inductive effect transmitted to the first layer could not interpret our experimental results reasonably. Thus, the model that the inductive effect passed on to a higher layer was proposed by investigating regression of the experimental results and the conclusion that the inductive effect transmitted to the third layer was drawn.
系统研究了不同种类的聚苯乙烯基大孔吸附树脂（MARs）在恒温条件下对芦丁的吸附特性。与传统的吸附模式（朗缪尔和弗伦德利希吸附）不同，结果显示出了有趣的方面：（1）随着初始溶液体积的增加，吸附容量先增加到最大值，然后逐渐减少。（2）实验结果清楚地证实了这样一种观点，即 MARs 的吸附过程可以通过在两个交点处发生的毛细作用分为三个阶段——大孔、中孔和微孔，并且每个阶段的吸附特性都可以用第四种 Brunauer 模型很好地描述。（3）感应效应传递到第一层的模型不能合理地解释我们的实验结果。因此，通过考察实验结果的回归，提出了感应效应传递到更高层的模型，并得出感应效应传递到第三层的结论。
