Novel highly reactive and regenerable carbon/iron composites prepared from tar and hematite for the reduction of Cr(VI) contaminant

Highly reactive carbon/Fe composites were prepared from tar used as a carbon source, and hematite (α-Fe2O3), a widespread naturally available iron oxide. Tar was impregnated on hematite and thermally treated under N2 atmosphere. Mössbauer, powder X-ray diffraction and magnetization data suggested th
