Dual-purpose ferric chloride was successively used as a catalyst and iron source for ferric oxide to conveniently prepare a magnetic Fe3O4/HCPBn-glu polymer with tetrabenzylglucose as the precursor. First, ferric chloride was employed as a Friedel–Crafts reaction catalyst for the synthesis of hyper-cross-linked HCPBn-glu. Subsequently, the ferric chloride was utilized as an iron source for the synthesis of Fe3O4 magnetic nanoparticles by coprecipitation, which anchored Fe3O4 nanoparticles onto the HCPBn-glu skeleton. A variety of modern analytical techniques were used to characterize prepared Fe3O4/HCPBn-glu. The effects of adsorbent amount, contact time, and pH were studied, and this composite showed excellent adsorption performance for 2,4-dinitrophenol (DNP), with a maximum adsorption capacity of 83.3 mg/g and removal efficiency of 91.7%. The adsorption of DNP is well fitted by the Freundlich model, indicating multilayer adsorption. The adsorption kinetics obey a pseudo-second-order kinetic model. In addition, Fe3O4/HCPBn-glu can be reused for at least six cycles with an acceptable removal efficiency, making it an economically valuable adsorbent. The adsorption mechanism was also discussed, and hydrogen bond, hydrophobic, and π–π interactions may be responsible for DNP adsorption. Based on these results, Fe3O4/HCPBn-glu can be utilized as an effective adsorbent for the removal of nitrophenols from sewage.

双作用氯化铁简便合成磁性葡萄糖基超交联聚合物用于去除污水中的硝基苯酚
先后采用两用三氯化铁作为催化剂和三氧化二铁的铁源，以四苄基葡萄糖为前驱体，方便地制备了磁性Fe 3 O 4 /HCP Bn-glu聚合物。首先，采用氯化铁作为弗里德尔-克来福特反应催化剂来合成超交联的 HCP Bn-glu。随后，以氯化铁为铁源，通过共沉淀法合成Fe 3 O 4磁性纳米颗粒，将Fe 3 O 4纳米颗粒锚定在HCP Bn-glu骨架上。使用多种现代分析技术来表征制备的Fe 3 O 4 /HCP Bn-glu。研究了吸附剂用量、接触时间和pH值的影响，该复合材料对2,4-二硝基苯酚（DNP）表现出优异的吸附性能，最大吸附容量为83.3 mg/g，去除效率为91.7%。DNP 的吸附符合 Freundlich 模型，表明多层吸附。吸附动力学遵循准二级动力学模型。此外，Fe 3 O 4 /HCP Bn-glu可以重复使用至少六个循环，具有可接受的去除效率，使其成为一种具有经济价值的吸附剂。还讨论了吸附机制，氢键、疏水性和π-π相互作用可能是DNP吸附的原因。基于这些结果，Fe 3 O 4 /HCP Bn-glu可以用作去除污水中硝基酚的有效吸附剂。
