Abstract: Introduction. In this paper, an experiment made with the degradation of the Recoltive red dye with titanium dioxide, peroxide and phenton using the UV lamp as a medium, is presented. The tests made involved the variation of the quantities of these oxidants. Objective. To compare the treatments with titanium dioxide and phenton for colored waste water. Materials and methods. The equipment used consisted of a 41 cm x 25,5 cm x 20 cm glass bucket that contained 15L of sample; a MIGHTY PURE ultra violet lamp 60 Hz and a pump that drives a 0,047 L/s flow. The dye was added in the tank and then the concentration was 100 mg/L. The pH was continuously measured in order to adjust it in 5,0.When phenton and TiO2 were used, either acids or bases were required to measure the pH values, because they were more stable. Results. The best combination to treat water from textile industries with UV light lamp and titanium dioxide is 100 mg/L of TiO2 and 2% v/v of H2O2. The test with the optimal degradation of the color was that with phenton, 30 mg/L of FeCl3 and 1% v/v of H2O2. Conclusions. The use of advanced oxidation processes such as photo catalysis with TiO2 or photo phenton, had different results concerning the reduction of the dye´s degradation percentage and higher reaction speeds. The photo phenton reaction was the one with the best percentages and reduction time periods (E13 with 30 mg/L FeCl3 and 1% v/v of H2O2).
