Green Synthesis of Iron Nano Particles Using Fennel (Foeniculum vulgare) Extract and its Antioxidant Properties
Typical nanoparticle synthesis methods have disadvantages such as poor structure, low production rate, high production cost and high energy requirement. Therefore, today the tendency to use plant resources as one of the most suitable methods of nanoparticle synthesis is taken into consideration by researcher attention. Foeniculum vulgare is one of the most important medicinal plants in Iran that has the potential to synthesize nanoparticles from its seed or shoot extracts. In this study, the possibility of green synthesis of zero iron nanoparticles using fennel seed extracts was investigated.
In this study, seed extract was used to synthesize green nanoparticles of iron particles.The antioxidant properties and the total amount of phenolic compounds of seed extract and extract containing nano-iron particles were determined. Structural analysis of iron nanoparticles was performed using scanning electron microscopy.
The formation of iron nanoparticles was confirmed by changing the color of the solution from yellow to brown. Both in the extract containing the seeds and in the extract containing iron nanoparticles, antioxidant properties were observed and adding iron nanoparticles increased the antioxidant properties of fennel. Structural analysis of iron nanoparticles using scanning electron microscopy showed that the shape of spherical particles and its dimensions are 200 nm.
The results of this experiment showed that the fennel seed extract can be used to synthesize nanoscale zero-valent iron particles, and increasing the Zero nanoparticles increases its antioxidant properties. Received
