| 中文摘要: |
| 红背桂树叶提取物绿色合成铁纳米颗粒（Fe NPs）在水环境修复领域具有很高的应用潜力。但由于Fe NPs存在团聚、易氧化等不稳定因素，在去除污染物时抑制了反应活性。为了解决这一问题，使用一步法制备了高岭土负载Fe NPs （K-Fe NPs），并系统地检测了其对孔雀石绿和Pb2+混合污染物的去除反应活性。采用X射线衍射（XRD）和傅里叶红外光谱（FTIR）对Fe NPs、高岭土和K-Fe NPs进行表征和分析。3种材料对比实验结果表明，K-Fe NPs对单独的孔雀石绿和Pb2+的去除效率（99.10%和93.41%）优于Fe NPs（93.67%和85.33%）和高岭土（32.54%和12.50%）。此外，K-Fe NPs经过4次重复循环对孔雀石绿和Pb2+的去除率仍分别为74.02%和55.48%。结果表明，K-Fe NPs在染料和重金属离子复合污染修复领域具有一定应用前景。 |

| Green synthesized iron nanoparticles （Fe NPs） by Euphorbia Cochinchensis extract have high application potential in the field of water environment remediation. However, due to the agglomeration, easy oxidization and other unstable factors of Fe NPs, the reaction activity was inhibited in the removal of pollutants. To solve this problem, kaolin-supported Fe NPs (K-Fe NPs) were prepared and their reaction activity has been tested systematically on the removal of mixed contaminants malachite green and Pb2+. X-ray diffraction (XRD) and Fourier Translation Infrared Spectroscopy (FTIR) were used to characterize Fe NPs, Kaolin, and K-Fe NPs. The comparative experiment results of three materials demonstrated that the removal efficiency on individual malachite green and Pb2+ using K-Fe NPs (99.10% and 93.41%) was better than Fe NPs (93.67% and 85.33%) and Kaolin (32.54% and 12.50%). Furthermore, the removal efficiencies of four reuse cycles were still 74.02 % and 55.48% on malachite green and Pb2+ respectively. In conclusion, K-Fe NPs has certain application prospects in the field of dye and heavy metal ion composite pollution remediation. |
