چکیده :

Today, the synthesis of iron nanoparticles by green synthesis method without using chemicals has received a lot of attention. One of the most important methods of synthesis is the production of metal nanoparticles using medicinal plants. Due to the disadvantages of chemical and physical methods of nanoparticle synthesis, such as weak structure, low production rate, and high production cost, researchers use plant sources as the most suitable method for nanoparticle synthesis. In this research, the extract of watercress (Nasturtium officinale) was used to investigate the synthesis of iron nanoparticles. In this study, for the synthesis of iron nanoparticles, a solution of iron chloride was added to the aqueous extract of the aerial parts of watercress. The synthesis of iron nanoparticles was investigated by changing the color of the solution and using spectrophotometry and FTIR spectroscopy. In the obtained results, the formation of iron nanoparticles was confirmed by changing the color from yellow to brown after adding iron chloride to watercress extract. Also, infrared spectrum analysis of formed nanoparticles showed the presence of different functional groups. The formation of iron nanoparticles was done by examining its absorption spectrum by UV-Vis spectrophotometer in the wavelength range of 200 to 600 nm.
