This paper presents the evaluation of iron oxide nanoparticles obtained from the aqueous extract of Eucalyptus grandis. 23 experiments were performed where the synthesis of nanoparticles was carried out by using the aqueous extract together with salts of iron (II) chloride tetrahydrate and iron (III) chloride hexahydrate. Characterization was carried out using IR, TEM and BET, where bands at 3440.77, 1559.26 and 445.31 cm-1 were presented, indicating the presence of iron oxide nanoparticles. Relatively high monodispersity with particles around 9 nm was evident. By means of BET analysis it was found that it presents a surface area of 131,897 m2 / g. The obtaining of nanoparticles by this green method presents yield values around 98%, with application in nanotechnology, biomedicine, environmental treatment, among others, for which they are highly versatile and their production cost is relatively low.

Palabras clave : green synthesis; magnetite nanoparticles; vegetal extract.
