In this study, green synthesis of iron oxide magnetite (Fe 3 O 4 -NPs) was successfully prepared from Artemisia leaves extract and Assessment of Their Antioxidant Activities. The effect of different ferric chloride concentrations 0.01-0.1 M on the nanoparticles’ iron oxide formation was studied. The obtained Fe 3 O 4 nanoparticles were characterized using various techniques, such as UV–Visible, FT-IR, XRD, SEM and EDAX are used for this purpose. The antioxidant activity of Fe 3 O 4 -NPs was determined by total antioxidant capacity (TAC), DPPH• (2, 2- diphenyl-1-picrylhydrazyl), FRAP (Ferric ion reducing antioxidant power assay) assays. In addition, UV–Vis spectra showed maximum absorption at range 275–301 nm related to the Fe 3 O 4 -NPs. FTIR spectra exhibit a two weak peak at 510 and 594 cm −1 attributed to Fe 3 O 4 -NPs vibration, confirming the formation nanoparticles XRD confirmed the crystalline nature of Fe 3 O 4 -NPs with average size ranged in 19–24 nm. SEM showed that the green synthesizing magnetite nanoparticles having in general as cubical shape. The purpose of this study, it highlights the high antioxidant activity of magnetite Fe 3 O 4 -NPs green synthesized, as a result, the use of Artemisia leaves extract offers its ease, fast, low-cost and friendly to the environment compared to other synthesis methods.
