Abstract Abstract: Three-dimensional .owerlike nanostructured metal oxides attached on the surfaces of Fe-based multi-phase nanocrys-talline ribbons (Fe-MNRs) were prepared by a simple way (through immersing the Fe-MNRs in Orange II solution). It has been found that the as-prepared Fe-MNRs with 3D .owerlike nanostructures (Fe-MNRs ? FNs) exhibit good absorption property for a typical heavy metal ion (CrVI) in wastewater, while Fe-MNRs do not possess such properties. The Fe-MNRs ? FNs could remove 99% CrVI ions from the solution in 40 min, and this adsorption property can be attributed to the ion exchange between CrVI and surface hydroxyl groups (O�CH) of 3D .owerlike nanostructures. The present result suggests that the Fe-MNRs ? FNs, prepared by facile way, possess great potentials in removing heavy metallic ions in wastewater.
