N2 - Iron oxide nanoparticles (NP FeO) have been synthesized using the green chemistry method, a sustainable method because it involves the minimum use of highly polluting chemical reagents, reducing only to the use of the precursor agent and the extract in 96% alcoholic solvent of eucalyptus (Eucalyptus globulus), this solvent was shown to have excellent reducing properties due to the metabolites it contains. In this sense, the colloid has been evaluated by UV-Vis spectrophotometry, obtaining an absorbance peak at 391.2 nm, typical for this type of nanomaterial, as well as a high stability as a result of the temporal evaluation of the colloid. The nanoparticle formation mechanism was evaluated by FTIR, which partially verified that the groups corresponding to aromatic and aliphatic compounds would be involved in the NP FeO formation process. The aforementioned nanoparticles have been applied to samples of agricultural soil contaminated with heavy metals (Cr, Cd and Pb), with the aim of evaluating the potential removal effect of metallic pollutants, the results suggest the definitive removal of Cr and Cd.
