The classic elimination methods used for textile dyes are not useful due to the fact that partial oxidation or mineralization can generate highly toxic by-products. A great quantity of the dyes is not directly toxic for living organisms, but their presence must be controlled because the coloring on the discharge media can suppress photosynthesis in water. Objective. To select the optimal photo sensitizer and oxidation agent quantities too degrade red Novactive F6BS analyzed with surface responses. Materials and methods. A 60 Hz MIGTHY PURE ultra violet lamp was used, along with a glass bucket with 15L of the simple. This sample was re-circulated with a pump which had a 0.047 L/s flow. Results. The best results obtained for the red Novactive F6BS were 76.2% of degradation and 49.4% of mineralization in two hours, with the E7 test (60 mg/L de FeCl3 and 1 mL/L of H2O2).Conclusions. The dye is more rapidly degraded and mineralized with FeCl3; This took place in the E7 test (60 mg/L FeCl3 and 1.0 mL/L of H2O2).otherCorporación Universitaria LasallistaÁrea Metropolitana del Valle de AburráFotodegradaciónColorantes textilesColorante rojo novactiveContaminaciónContaminación del aguaContaminación industrialArticle
