RAMIREZ-FRANCO, José Herney  e  ZEA-RAMIREZ, Hugo Ricardo. Decontamination of industrial textile wastewater using photocatalysis. Dyna rev.fac.nac.minas [online]. 2016, vol.83, n.196, pp.80-85. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v83n196.47446.

Iron-doped TiO₂ catalysts were prepared by impregnation in order to study their photocatalytic activity in the treatment of wastewater from the textile industry. Characterization of the catalysts before and after reaction was performed using techniques including total surface area measurement, X-Ray diffraction and elemental analysis via X-Ray fluorescence. Varying pH conditions, H₂O₂ concentrations and catalyst quantities were evaluated during the photocatalytic reactions. Fe-TiO₂ catalysts were shown to be highly active in the reduction of chemical oxygen demand (% COD) and % color reduction in the water treated.
