| 摘 要： | 利用AM1半经验计算法计算出用不同官能团修饰的聚苯乙烯型吸附树脂的前线轨道能量值.设计筛选出合适的官能团,根据吸附质的分子尺寸,修饰合成出具有匹配孔径、较大比表面积的吸附树脂.在303K下,测定了它们对不同取代基的酚类化合物的吸附等温线.以Amberlite XAD-4作参照,比较了吸附剂的吸附效果,并阐明了吸附机理.

| Abstract: | The frontier orbital energy values of adsorption resins of polyvinyl benzene modified by different functional groups were calculated with the semi-empirical method of AM1, and the satisfactory groups were designed. Based on the dimension of the adsorbates, the resins having the high specific surface and matched porous radius were prepared. The adsorption isotherms of phenolic compounds were determined at 303K. The adsorption efficiencies of different adsorbents were compared with those of Amberlite XAD-4, and the adsorption mechanism was elucidated. |
