Green Synthesis Of Iron Oxide Nanoparticles By Aqueous Leaves Extract Of Mentha Pulegium L.: Effect Of Ferric Chloride Concentration On The Type Of Product

Résumé: In this study, green synthesis of iron oxide nanoparticles was successfully prepared from Mentha pulegium L. leaves extract. The effect of different ferric chloride concentrations on the nanoparticles' iron oxide formation was studied. The obtained nanoparticles were characterized by UV-Vis, FT-IR, XRD, SEM and EDAX techniques are used for this purpose. UV-Vis spectra showed maximum absorption at range 275–301 nm related to the iron oxide. FTIR spectra exhibit a two weak peak at 510 and 594 cm−1 attributed to iron oxide NPs vibration, confirming the formation nanoparticles XRD confirmed the crystalline nature of Fe3O4 and α-Fe2O3 NPs with average size ranged in 22–34 nm. SEM showed that the green synthesizing Iron oxide nanoparticles having in general as cubical shape. As a result, the use of Mentha pulegium L. leaves extract offers its ease, fast, low cost and friendly to the environment compared to other methods.
