摘要
摘要 含有金属的纳米颗粒在废水处理方面效果显著。使用磁性材料可以有效地将吸附剂从溶液中分离出来。在这项工作中，合成了磁性氧化铁纳米粒子，并用聚乙二醇对其进行改性以形成稳定的悬浮液。通过 X 射线衍射分析、透射电子显微镜、傅立叶变换红外光谱和振动样品磁力计研究了所获样品的结构和磁性能。结果表明，在表面改性过程中，通过改变磁性纳米粒子和聚乙二醇的比例，可以获得一种复合材料，其在 1.2 T 磁场中的磁化值在 10-17 A m2/kg 范围内，样品中磁性纳米粒子的质量含量为 19-33%。对所得样品进行了从溶剂中去除亚甲基蓝的测试，证明了它们作为有效吸附剂的潜力。此外，这些纳米颗粒对人体细胞没有细胞毒性。
PEGylated Iron-Oxide Nanoparticles: Structural, Magnetic, and Sorption Properties
Metal-containing nanoparticles are shown to be effective in wastewater treatment. The use of magnetic materials allows for efficient separation of the sorbent from the solution. In this work, magnetic iron-oxide nanoparticles are synthesized and modified with polyethylene glycol to form a stable suspension. The structural and magnetic properties of the obtained samples are investigated by X-ray diffraction analysis, transmission electron microscopy, Fourier-transform infrared spectroscopy, and vibrating sample magnetometry. The results show that by varying the ratio of magnetic nanoparticles and polyethylene glycol during surface modification, it is possible to obtain a composite material with a value of the magnetization in a field of 1.2 T in the range of 10–17 A m2/kg with a mass content of magnetic nanoparticles in samples of 19–33%. The resulting samples are tested for the removal of methylene blue from a solvent, demonstrating their potential as effective sorbents. Additionally, these nanoparticles showed no cytotoxicity on human cells.
