以芦丁为吸附剂，系统研究了不同种类聚苯乙烯基大孔吸附树脂（MARs）在恒温条件下的吸附特性。与传统吸附模式不同，Langmuir和Freundlich吸附的结果显示出以下有趣的方面：(1)随着初始溶液体积的增大，吸附容量增大到最大值，然后逐渐减小；(2)实验结果清楚地验证了火星吸附过程可分为大孔、中孔和微孔三个阶段的观点，并且第四类Brunauer模型可以很好地描述每个阶段的吸附特征。(3)感应效应传递到第一层的模型不能合理解释我们的实验结果。因此，通过对实验结果的回归研究，提出了诱导效应向更高层传递的模型，并得出了诱导效应向第三层传递的结论。
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.
