RESUMO:

The most easily detected emerging pollutants in the aquatic environment are antibiotics and dyes, the first to have a refractory feature making it difficult to effectively remove wastewater from sewage and treatment plants, the second to be produced and used on a large scale in several industrial stages. On this context, there is a need for the application of advanced techniques for the degradation/removal of these pollutants that are in environment and will, in the long term, cause resistance to drugs and cancer in humans. In this study was done the treatment by anodic oxidation and electro- fenton of synthetic effluents contaminated with a drug used to Tuberculosis, Rifampicin and the other contaminated with the Brilliant Blue FCF using Boron Doped Diamond (BDD) electrodes and Carbon Felt (CF). The effect of the application of different currents on the degradation and the influence of the initial concentration of the pollutant were examined. Comparative studies using other commercial electrode materials were also investigated, as was the evaluation of the efficiency of different electrolytes. The degradation of rifampicin had better results with the BDD / CF material at current density of 50 mAcm^-2, achieving 98% COD removal. While the removal of Brilliant Blue had good results from the application of the current of 250 mA for 6 hours, depending on the initial concentration, reaching current efficiency of 93%.
