ABSTRACT

Iron oxide (Fe880O) nanoparticles (IONPs) were synthesised via a chemical reaction by mixing hot red pepper with waste rust iron extract at 300°C for 1.5 hours to study the resulting antibacterial activity. The structural and optical properties of the NPs were characterised using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), UV-visible spectroscopy (UV-Vis), and Fourier-transform infrared spectroscopy (FTIR). The antibacterial activity of the IONPs was examined in comparison with that of gram-positive; Staphylococcus aureus, Bacillus subtilis, and gram-negative; and Escherichia Coli and Klebsiella pneumonia bacteria. Additionally, this information was used to investigate the accumulation of spent iron extract from the environment, its conversion into an efficient basic material to synthesise Fe880O NPs, and their utility for medical treatments. The results yielded important information regarding the properties of IONPs (e.g. crystallite size, particle size, energy band gap, and absorption band strength) and their inhibition on both bacterial strains. Finally, this research will pave a new path for exploring how to utilise rust iron and transform it from harmful to beneficial material.

将辣椒与锈铁提取物混合合成氧化铁纳米颗粒以检测抗菌活性

摘要

氧化铁 (Fe 880 O) 纳米粒子 (IONPs) 通过将红辣椒与废锈铁提取物在 300°C 下混合 1.5 小时,通过化学反应合成,以研究由此产生的抗菌活性。使用 X 射线衍射 (XRD)、场发射扫描电子显微镜 (FE-SEM)、紫外-可见光谱 (UV-Vis) 和傅里叶变换红外光谱 (FTIR) 对纳米颗粒的结构和光学性质进行了表征。IONPs 的抗菌活性与革兰氏阳性菌比较;金黄色葡萄球菌、枯草芽孢杆菌和革兰氏阴性菌;和大肠埃希菌肺炎克雷伯菌细菌。此外,该信息用于研究环境中废铁提取物的积累,将其转化为合成 Fe 880 O NPs 的有效基础材料,以及它们在医学治疗中的用途。结果产生了有关 IONP 的特性(例如微晶尺寸、粒度、能带隙和吸收带强度)及其对两种细菌菌株的抑制作用的重要信息。最后,这项研究将为探索如何利用锈铁并将其从有害物质转化为有益物质铺平新的道路。
