| 摘 要： | 以对硝基苯胺作吸附质、对羟基苯甲酸修饰的吸附树脂CS-6作为吸附剂，超高交联吸附剂Jx-101作为参照物，研究Jx-101、CS-6对对硝基苯胺的吸附能力。CS-6、JX-101对对硝基苯胺的吸附等温线表明：CS-6对对硝基苯胺的吸附能力强于JX-101。比较了CS-6、JX-101吸附剂对正己烷溶液中的对硝基苯胺吸附前后红外光谱。结果表明：CS-6吸附剂在吸附对硝基苯胺过程中，吸附前后树脂的红外光谱的特征吸收峰发生明显的漂移，这是由于对羟基苯甲酸与对硝基苯胺分子之间发生酸碱配合作用的结果。

| Abstract: | In this paper,polystyrene-based adsorbents chemically modified p-hydroxybenzonic acid(denoted CS-6) was synthesized for enhanced removal of p-nitroaniline from aqueous solution.A commercial styrene-divinylbenzene hyper-cross-linked polymeric sorbent JX-101 was selected as the reference to evaluate the performance of CS-6.The p-nitroaniline stronger capacity onto CS-6 than that onto JX-101 was observed by comparing with their isotherm at same situation.Comparing with the infrared spectrum of CS-6 before and ... |
