摘要

:通过 N, N, N', N'-tetrakis(4- aminophenyl)-1,4-benzenediamine, 4, 4-biphenylldialdehyde 和 isophthalaldehyde 反应制备了两种聚合物颗粒，并通过扫描电镜、傅立叶变换红外光谱和 XRD 进行了表征。以亚甲基蓝为模型污染物，采用不同的吸附剂用量、吸附时间和吸附温度，观察了两种聚合物颗粒的吸附性能。实验数据表明，聚合物 A 和聚合物 B 对亚甲蓝废水的去除率分别为 74% 和 68%，而经过光催化处理后，聚合物 A 和聚合物 B 的去除率分别高达 84% 和 74%。此外，两种席夫碱产品对亚甲基蓝的吸附均符合弗伦德里希吸附等温模型。

Preparation and Adsorption Properties of Polymer Particles based on N, N, N', N'-Tetrakis(4-aminophenyl)-1,4-Benzenediamine

: Two polymer particles have been prepared by the reaction of N, N, N', N'-tetrakis(4- aminophenyl)-1,4-benzenediamine, 4, 4-biphenyldialdehyde and isophthalaldehyde, and characterized by SEM, FTIR and XRD. Based on methylene blue as the model pollutant, the adsorption properties of two polymer particles have been observed by using different adsorbent dosages, adsorption times and adsorption temperatures. Experimental data show that the removal rates of methylene blue wastewater are 74 % for polymer A and 68 % for polymer B, and the removal rates are up to 84% for polymer A and 74 % for polymer B after photo-catalytic treatment. All these suggest that the adsorption performance of polymer A is more excellent than that of polymer B. In addition, the methylene blue adsorption of the two Schiff base products conforms to the Freundlich adsorption isothermal model.
