摘要

摘要本研究采用绿色简便的方法合成了磁性Fe3O4@SiO2-NH2（FSN）纳米复合吸附剂。利用 X 射线衍射（XRD）、透射电子显微镜（TEM）、傅立叶变换红外光谱（FTIR）和振动样品磁强计（VSM）对 FSN 吸附剂进行了表征。FSN 纳米复合材料表现出优异的 Zn2+ 吸附能力。此外，还研究了 FSN 纳米复合材料对 Zn2+ 的吸附动力学、等温线和吸附机理。FSN 纳米复合材料具有吸附速率快、分离过程简单、环境友好等特点，适用于水和废水的净化。

High-Performance Magnetic Fe3O4/SiO2-NH2 Nanocomposites: Synthesis and Application for the Removal of Zn2+ Ions from Water

In this study, magnetic Fe₃O₄@SiO₂-NH₂ (FSN) nanocomposite adsorbent was synthesized using a green and convenient method. The FSN adsorbent was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier-transform infrared (FTIR) spectroscopy, and vibrating-sample magnetometry (VSM). The FSN nanocomposites exhibit excellent Zn²⁺ adsorption capacity. In addition, adsorption kinetics, isotherms, and adsorption mechanism of Zn²⁺ on the FSN nanocomposites were also studied. The FSN nanocomposites show rapid adsorption rate, easy separation process, and environmental friendliness, which are suitable for water and wastewater purification.
