| Summary: | <p class="Default">This study aimed to use the following treatment technology: TiO<sub>2 </sub>photocatalysis and Fenton reaction for the remediation of mixture of textile dyes. For the photocatalytic treatment it was obtained a reduction in color of 80% and Chemical Oxygen Demand of 60% using for this 600 mg L<sup>-1</sup> of TiO<sub>2</sub>, 1500 mL min<sup>-1</sup> recirculation flow, temperature 40<sup> o</sup>C/45<sup> o</sup>C and pH = 6.3 for 60 minutes of treatment. By Fenton reaction it was reached color reduction at 95% and Chemical Oxygen Demand reduction at 75% employing 60 mg L<sup>-1 </sup>H<sub>2</sub>O<sub>2</sub>, 50 mg L<sup>-1</sup> de Fe<sup>2+</sup> and pH = 4.0 for 62 minutes of treatment.</p> |
