摘要/Abstract

摘要：

利用二乙醇胺(DEA)对氯甲基化聚苯乙烯基树脂(PS-Cl)进行表面改性, 制备了亲水性的PS-DEA树脂, 然后以FeCl₃·6H₂O和FeSO₄·7H₂O为前驱体通过共沉淀法原位复合制备了磁性PS-DEA树脂. 表征了磁性PS-DEA样品的形貌、结构以及磁性能, 研究了PS-DEA和磁性PS-DEA对水溶液中Hg(Ⅱ)的吸附性能. 结果表明, 含有Fe₃O₄的磁性PS-DEA树脂的比饱和磁化强度(M_s)为0.92 A·m²/kg, 磁性树脂中Fe₃O₄所占的质量分数为1.7%. 用Langmuir等温模型拟合了PS-DEA和磁性PS-DEA对水溶液中Hg(Ⅱ)的吸附数据, 计算得到最大吸附量分别为320.51和352.11 mg/g, 这表明磁性纳米粒子的引入有利于提高树脂的吸附性能, 这种磁性树脂有望作为吸附剂用于水处理领域.

Abstract:

The hydrophilic PS-DEA resins were prepared by diethanolamine(DEA) for the surface modifier of chloromethylation polystyrene resins(PS-Cl). In-situ magnetic PS-DEA composites were prepared by co-precipitation method with FeCl₃·6H₂O and FeSO₄·7H₂O as precursors. The morphology, structure and magnetic properties of the magnetic PS-DEA samples were characterized. The adsorption properties of PS-DEA and magnetic PS-DEA for Hg(Ⅱ) in aqueous solution were investigated by batch methods. The results showed that the magnetic PS-DEA with magnetic Fe₃O₄ were prepared. The saturation magnetization(M_s) of the magnetic PS-DEA was 0.92 A·m²/kg, and the Fe₃O₄ contents of the magnetic PS-DEA were 1.7%(mass fraction). The adsorption data of PS-DEA and magnetic PS-DEA for Hg(Ⅱ) in aqueous solution were fitted using Langmuir isothermal model, respectively. The maximum adsorption capacities of PS-DEA and magnetic PS-DEA for Hg(Ⅱ) were 320.51 and 352.11 mg/g, respectively, which demonstrated that the adsorption property of the PS-DEA resin was improved after introducing the magnetic nanoparticles. The obtained magnetic PS-DEA could be used as a promising magnetic adsorbent in waste water treatment.
