This project is focuses on novel, cost effective and simple plant mediated synthesis of silver nanoparticles (Ag-NPs) using leaf extract of Albizia procera. The optical, structural and physical properties of green synthesized Ag-NPs have been investigated by UV-Visible spectroscopy, X-ray Diffraction (XRD) and Atomic Force Microscopy (AFM), respectively. Prepared Ag-NPs are spherical in shape and crystalline in nature with an average size of 6.18 nm. Ag-NPs have showed promising potential in removal of organic pollutant methylene blue (MB) dye. Careful investigation on the removal of dye as a function of contact time, UV light and exposure time, dose of nanoparticles, temperature and pH have also been carried out. Moreover, Ag-NPs exhibit outstanding antibacterial activities against gram negative Escherichia coli (E. coli) and gram positive Staphylococcus aureus (S. aureus) bacterial pathogens.
本项目专注于使用非洲桃花心木叶提取物，通过新颖、经济实惠且简单的植物介导方法合成银纳米粒子（Ag-NPs）。通过紫外-可见分光光度法、X 射线衍射（XRD）和原子力显微镜（AFM）分别研究了绿色合成的 Ag-NPs 的光学、结构和物理性质。所制备的 Ag-NPs 呈球形，具有晶体性质，平均粒径为 6.18nm。Ag-NPs 在去除有机污染物亚甲基蓝（MB）染料方面表现出了很有前景的潜力。还对染料的去除作为接触时间、紫外光和暴露时间、纳米粒子剂量、温度和 pH 值的函数进行了仔细研究。此外，Ag-NPs 对革兰氏阴性大肠杆菌（E. coli）和革兰氏阳性金黄色葡萄球菌（S. aureus）等革兰氏阳性细菌病原体表现出了出色的抗菌活性。
