Abstract

Introduction. Textile dyes have a great persistence in the environment and classic methods to eliminate them are useless due to the fact that oxidations or partial reductions can generate secondary products with high toxicity levels. Objective. To study the degradation and the mineralization of the Yellow Novactive F4GL dye with TiO2 and FeCl3, using the advanced oxidation processes with a ultra-violet light lamp and analyzing both the degradation and the mineralization by the use of a factorial model. Materials and methods. To make the tests a MIGHTY PURE 60 Hz ultra –violet light lamp was used, with a glass bowl which measured 41 cm x 25,5 cm x 20 cm and contained 15 L of sample. This system was complemented by a pump that had a 0,047 L/s flow. Each test was made three times, in order to reduce the experimental error. Results. The test with the highest degradation and mineralization levels was that with 60 mg/L FeCl3 and 1.0 mL/L of H2O2. It had a degradation percentage of 100 and a mineralization percentage of 70.1. Conclusion. Waste water with this dye is degraded and mineralized more rapidly with FeCl3 than with TiO2
