Resumo: | This work is a partnership with an ophthalmic products company that generates effluents containing a mixture of three dyes: blue 56, yellow 54 and red 60, all in the anthraquinone class. Dyes in this class are resistant to degradation due to their aromatic structure, which retains color for long periods of time. The treatment of these dyes is extremely important due to their toxicity, and may present carcinogenic and mutagenic behavior. The objective of this work was to oxidize polluting organic compounds using advanced oxidative processes. For this, constant current electrolysis was performed using oxide electrodes as heterogeneous catalysts together with Fenton's reagent (Fe2+ + H2O2). Discoloration and oxidation were monitored by UV-Visible spectrometry, high performance liquid chromatography and total organic carbon. The applied treatment allowed a rapid degradation of the chromophore groups and there was a great influence of the hydrogen peroxide concentration on the speed of this degradation. The results were satisfactory, since the coloration was eliminated and the oxidation products identified do not present toxicity and can be easily treated by traditional methods. |

Los tintes de esta clase son resistentes a la degradación debido a su estructura aromática, que retiene el color durante largos períodos de tiempo. El tratamiento de estos colorantes es de suma importancia por su toxicidad, pudiendo presentar un comportamiento cancerígeno y mutagénico. El objetivo de este trabajo fue oxidar compuestos orgánicos contaminantes mediante procesos oxidativos avanzados. Para ello, se realizó una electrólisis en corriente constante utilizando electrodos de óxido como catalizadores heterogéneos junto con el reactivo de Fenton (Fe2+ + H2O2). La decoloración y oxidación se controlaron mediante espectrometría UV-visible, cromatografía líquida de alta resolución y carbono orgánico total. El tratamiento aplicado permitió una rápida degradación de los grupos cromóforos y hubo una gran influencia de la concentración de peróxido de hidrógeno en la velocidad de esta degradación. Los resultados fueron satisfactorios, ya que se eliminó la coloración y los productos de oxidación identificados no presentan toxicidad y pueden tratarse fácilmente por métodos tradicionales.Este trabalho é uma parceria com uma empresa de produtos oftálmicos que gera efluentes contendo uma mistura de três corantes dispersos: azul 56, amarelo 54 e vermelho 60, todos da classe das antraquinonas.
