Using aqueous extract of Eucalyptus grandis to synthesize iron oxide nanoparticles

This work presents the evaluation of iron oxide nanoparticles obtained from aqueous extract Eucalyptus grandis. Twenty-three experiments were carried out where synthesis was performed by using together with salts (II) chloride tetrahydrate and (III) hexahydrate. A characterization IR, TEM BET, bands presented at 3,440.77, 1,559.26 445.31 cm−1, indicating presence nanoparticles. relatively high monodispersity evidenced particles around 9 nm. By means BET analysis it found to present a surface area 131.897 m2/g. Obtaining this green method yield values 98%, application in nanotechnology, biomedicine, environmental treatment, among others, making them highly versatile their production cost is low.
