文摘

γ-Fe2O3 nanoparticles were synthesized by Flame Spray Pyrolysis (FSP). γ-Fe2O3 nanoparticles were characterized and they remediated aqueous Pb2+ and Cu2+. Maghemite adsorption capacities of ∼69 (Pb2+ at 45 °C) and ∼34 (Cu2+ at 25 °C) mg/g were obtained. Likely Pb2+ and Cu2+ sorption mechanisms versus pH were described. γ-Fe2O3 nanoparticle application in ground water remediation was demonstrated.
