氨基功能化超交联聚合物的制备及其苯酚吸附性能研究

Fabrication of Amine-Appended Hyper-Cross-Linked Polymers for Phenol Adsorption

含酚废水广泛存在于化工及有机合成过程,其较强的毒性对水体环境造成了严重的危害。超交联聚合物(HCPs)作为一种有机多孔材料,近年来广泛应用于水体中有机污染物的脱除。为高效吸附分离含酚废水中的苯酚,氨基功能化的超交联聚合物通过付克烷基化反应一步制备。紫外吸收光谱被用于吸附前后水体中苯酚含量的检测,同时红外光谱表征了HCPs吸附前后材料表面的化学结构,简要分析了苯酚吸附过程的机理。

Phenol-containing wastewater widely exists in chemical and organic synthesis processes,and the strong toxicity of phenol will cause serious harm to the environment.As a kind of porous organic material,hyper-cross-linked polymers(HCPs)have been widely used to remove organic pollutants from aqueous solutions in recent years.To efficiently adsorb phenol from the wastewater,amino-appended hyper-cross-linked polymers were prepared by one-step Friedel-Crafts alkylation.The UV-Vis spectrum was used to detect the phenol content in the water before and after the adsorption.The IR spectrum was used to characterize the chemical structure of the material surface before and after the HCPs adsorption,and the mechanism of the phenol adsorption process was briefly analyzed.
