Nowadays, green synthesis methods have gained growing attention in nanotechnology owning to their versatile features including high efficiency, cost-effectiveness, and eco-friendliness. Here, the aqueous extract of leaf was applied for the preparation of iron nanoparticles (INPs) to obtain spherical and amorphous INPs with a particle size below 100 nm as confirmed by TEM. The synthesized INPs managed to eliminate methyl orange (MO) from the aqueous solution. The concentration of MO can be easily checked via ultraviolet-visible (UV-Vis) spectroscopy throughout the usage of INPs at the presence of HO. The synthesized INPs exhibited MO degradation efficiency of 77% after 6 h. Furthermore, the synthesized INPs exhibited antibacterial activity against both Gram-negative and Gram-positive bacteria. The prepared INPs have an impressive effect on at concentrations below 6 μg/ml. Overall, the synthesized INPs could considerably contribute to our combat against organic dyes and bacteria.
如今，绿色合成方法因其具有高效、成本效益高和环保等多种特性，在纳米技术领域受到越来越多的关注。在此，利用树叶的水提取物制备铁纳米颗粒（INPs），通过透射电子显微镜（TEM）确认获得了粒径小于100 nm的球形和无定形INPs。合成的INPs能够从水溶液中去除甲基橙（MO）。在HO存在的情况下，在整个使用INPs的过程中，可以通过紫外可见（UV-Vis）光谱轻松检测MO的浓度。合成的INPs在6小时后表现出77%的MO降解效率。此外，合成的INPs对革兰氏阴性菌和革兰氏阳性菌均表现出抗菌活性。制备的INPs在浓度低于6μg/ml时对……有显著效果。总体而言，合成的INPs对我们对抗有机染料和细菌有很大帮助。
