Abstract

Phyto-mediated synthesis can be used for the sustainable fabrication of metallic nanoparticles (NPs). Ethanolic leaf extract of Acacia jacquemontii was used to phyto-fabricate iron oxide nanoparticles (FeO NPs). Synthesized FeO NPs were examined by various analytical techniques for their detailed chemical elemental and morphological features. High-performance thin-layer chromatography (HPTLC) was used for the analysis of the ethanolic extracts of the leaves, which ensured the presence of phenols and terpenoids in the extract. FeO NPs show a peak between 350-400nm when analyzed by UV-Vis spectroscopy, and the typical bands were found in the range of 745 cm−1 for Fe-O and 1595 cm−1, 3177 cm−1 for some other organic molecules by Fourier transform-infrared (FTIR). The spherical shape of FeO NPs was investigated with the help of a Field emission scanning electron microscope (FESEM) analysis which exhibited the size varied from 13.35 to 31.29 nm. Electron diffraction spectroscopy (EDS) confirmed the Fe, O, and C peaks, along with N, Cl, S, and K traces. The adsorption capacity of the FeO NPs for brilliant green (BG) dye was evaluated at different pH, dosages of adsorbent, and contact time. The highest adsorption parentage of 57.2% for 10 ppm BG dye was observed at 9 pH and 10 mg doses of FeO NPs. The highest absorption capacity of FeO NPs is 60 mg/g. The recyclability potential of the FeO NPs continuously decreased with the repletion of the cycle from first to fourth whose value reached 19.33% after the fourth cycle. Such phytofabricated FeO NPs and their application in the removal of organic could prove to be eco-friendly and economical.

用金合欢叶提取物合成的氧化铁纳米颗粒对亮绿色染料的吸附。

植物介导合成可用于金属纳米颗粒的可持续制造。以金合欢叶乙醇提取物为原料，制备了氧化铁纳米颗粒。用各种分析技术对合成的FeO NPs进行了详细的化学元素和形态特征检测。采用高效薄层色谱法（HPTLC）对乙醇提取物进行分析，确保提取物中存在酚类和萜类物质。傅里叶变换红外（FTIR）分析发现，FeO NPs的典型谱带在350 ~ 400nm之间，Fe-O的谱带在745 cm-1范围内，其他有机分子的谱带在1595 cm-1、3177 cm-1范围内。利用场发射扫描电镜（FESEM）分析了FeO纳米颗粒的球形形状，其尺寸在13.35 ~ 31.29 nm之间。电子衍射谱（EDS）证实了Fe， O和C峰，以及N， Cl， S和K的痕迹。考察了FeO NPs在不同pH、吸附剂用量和接触时间下对亮绿染料的吸附能力。在9 pH和10 mg FeO NPs剂量下，10 ppm BG染料的最高吸附率为57.2%。FeO NPs的最高吸收容量为60 mg/g。FeO NPs的可回收潜力随循环次数从第1次到第4次不断降低，第4次循环后达到19.33%。这种植物合成的FeO NPs及其在有机物去除中的应用可能被证明是生态友好和经济的。
