Iron Sand - Zno Based Materials of Natural Origin for Dye Decolorization under Sunlight Irradiation

A mixed iron sand - ZnO materials was prepared by heating a mixture of natural iron sand and ZnO at 900 degrees C for 5 hours. XRD study of the sample revealed that, in the mixed iron sand - ZnO present some minor peaks that similar with XRD pattern of gamma-Fe2O3 and/or Fe3O4. Observation of the sample using SEM, showed a compact morpholgy and almost homogenenous in particles size. In purpose to evaluate the ability of this materials for textile dying wastewater treatment, a study on rhodamine B decolorization was carried out as a reperesentative.
