A series of macroporous adsorption resins (MARs) with novel structure were synthesized on the basis of the Friedel-Crafts catalyzed and amination reaction. Adsorption feature of the synthetic resins with respect to the purification effect were investigated systemically by employing rutin as the adsorbate. Different from traditional adsorption patterns, the results showed interesting conclusions: (1) With the increase in the temperature of the experiment, the adsorption capacity increased gradually; with the increase in the concentration of the initial solution, the adsorption capacity increased to the maximum and then decreased gradually. (2) The classical models that the inductive effect transmitted to the first layer and the adsorption process contained in one compartment could not explain our experimental results reasonably. Thus, a new adsorption isotherm model that the inductive effect passed on to a higher layer and a new adsorption kinetics model in which the adsorption process contained more compartments were created according to the multiparameter theory and Karickhoff's theory by investigating the regression of the experimental results. The conclusion that the inductive effect passed to the fourth layer and the adsorption process contained four compartments was drawn.
一系列具有新颖结构的大孔吸附树脂（MARs）是基于Friedel-Crafts 催化和胺化反应合成的。通过采用芦丁作为吸附剂，系统研究了合成树脂对纯化效果的吸附特性。与传统的吸附模式不同，结果显示出有趣的结论：（1）随着实验温度的升高，吸附容量逐渐增加；随着初始溶液浓度的增加，吸附容量先增加到最大值，然后逐渐减小。（2）经典模型认为诱导效应传递到第一层，吸附过程包含在一个隔室中，不能合理地解释我们的实验结果。因此，根据多参数理论和 Karickhoff 理论，通过对实验结果的回归，创建了一个新的吸附等温线模型和一个新的吸附动力学模型，其中吸附过程包含更多隔室。得出诱导效应传递到第四层，吸附过程包含四个隔室的结论。
