Sugar cane residues were used to obtain an activated carbon and hematite
composite. A 1 cm piece of sugar cane was left in contact with iron chlorides
(Fe 2+ /Fe 3+ ) solution in a 1:2 ratio, varying time of 24, 48 and 72 h. Subsequently,
two experiments were carried out: in the first, NH 4 OH was added for the
production of magnetite in the pores of the cane and the product was
carbonized at a temperature of 800 ° C for 6 h; for the second experiment no
chemical reagent was used only the carbonization process. The product
obtained was characterized by x-ray diffraction and infrared spectroscopy. The
diffraction results presented the typical phase of cubic hematite, however a shift
in the bands indicative of the presence of activated carbon is observed. These
results were compared with those obtained via FT-IR finding that a compound
between carbon and hematite had actually formed. Finally, the product will be
tested for removal of inorganic contaminants.
