Enhanced removal of Cr(VI) from aqueous solution by stabilized nanoscale zero valent iron and copper bimetal intercalated montmorillonite.

Batch experiments were conducted to study the Cr(VI) removal by nanoscale zero valent iron and copper intercalated montmorillonite (MMT-nFe/Cu) nanocomposite. MMT-nFe/Cu was characterized using SEM, TEM, XRD, FTIR, N adsorption-desorption isotherms and XPS. The results demonstrated that highly dispersed nanoscale Fe/Cu (nFe/Cu) were successfully introduced into the montmorillonite (MMT) layers.
