Reduced graphene oxide/iron nanoparticles used for the removal of Pb (II) by one step green synthesis.

While nanomaterials are increasingly being proposed for contaminant remediation, a major challenge is how to develop high removal functionality while maintaining low cost and environmental friendliness. In this study, a hybrid reduced graphene oxide/iron nanoparticle (rGO/Fe NPs) was prepared via the in situ reduction of GO and FeCl by eucalyptus leaf extract in one-pot. The obtained rGO/Fe NPs could rapidly remove 72.
