dc.description.abstractIron mining residues were successfully used in the fast and inexpensive sol-gel synthesis of magnetic hybrids (CoFe2O4/NOM), with water rich in natural organic matter (NOM) as solvent. XRD analyses revealed formation of the cobalt ferrite phase, while SEM and TEM images showed the formation of nanostructures. The hybrids obtained (HbSF and HbLM) provided excellent rates of conversion (99%) of nitrophenol in short times of 50 and 120 s, respectively. The hybrids also showed high performance in the adsorption of PAHs, achieving removals of 75–88% (HbSF) and 72–81% (HbLM). This work contributes to the conversion of industrial operations from linear to cyclic processes.en
