摘要

本研究探讨了以油棕(Elaeis guineensis)残渣为还原剂绿色合成纳米银粒子(Ag NPs)的方法。采用Taguchi L9设计,通过分析pH、硝酸银(AgNO3)浓度和萃取物与AgNO3比的影响,对合成工艺进行了优化。在pH值为10、AgNO3浓度为100 mM、萃取物与AgNO3的比例为2:3的条件下,得率最高(72%)。通过紫外-可见光谱(400-450 nm)、傅里叶变换红外光谱(FT-IR, 1370 cm-1,归属于硝基)、动态光散射(DLS,平均粒径10.07 nm,中性pH下水动力直径(Dh)为235.82 nm)、zeta电位(−18.33 mV)、扫描电镜(SEM)和x射线衍射(XRD)对合成的Ag-NPs进行了表征。对铜绿假单胞菌的抗菌测试显示出抗菌活性,使这些纳米颗粒成为传统抗生素的有希望的替代品。图形抽象

Optimization of silver nanoparticles synthesis using Elaeis guineensis Jacq. residue extract and their antibacterial activity against Pseudomonas aeruginosa

This study explores the green synthesis of silver nanoparticles (Ag NPs) using oil palm (Elaeis guineensis) residue as a reducing agent. The synthesis was optimized by analyzing the effects of pH, silver nitrate (AgNO3) concentration, and extract-to-AgNO3 ratios using a Taguchi L9 design. The highest yield theorist (72%) was achieved under the conditions of pH 10, 100 mM AgNO3 concentration, and a 2:3 extract-to-AgNO3 ratio. The synthesized Ag-NPs were characterized through UV–Vis (400–450 nm), Fourier-transform infrared spectroscopy (FT-IR, 1370 cm-1, attributed to the nitro group), dynamic light scattering (DLS, 10.07 nm average particle size with a hydrodynamic diameter (Dh) of 235.82 nm in a neutral pH), zeta potential (− 18.33 mV), scanning electron microscopy (SEM), and X-ray diffraction (XRD). Antimicrobial testing against Pseudomonas aeruginosa revealed antibacterial activity, making these nanoparticles a promising alternative to traditional antibiotics.
