REMEDIATION OF TEXTILE DYES MIXTURES USING TIO2/VIS PHOTOCATALYSIS AND FENTON FE2+/H2O2

<p class="Default">This study aimed to use the following treatment technology: TiO₂photocatalysis 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^-1 of TiO₂, 1500 mL min^-1 recirculation flow, temperature 40^oC/45^oC 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^-1H₂O₂, 50 mg L^-1 de Fe²⁺ and pH = 4.0 for 62 minutes of treatment.
