Tratamiento fotocatalítico de una disolución acuosa de azocolorante Negro Ácido 52 utilizando como catalizador diferentes mezclas de óxidos semiconductores
In this study, the photocatalytic degradation of azo dye Acid Black 52 using different mixtures of semiconductor oxides as a catalyst is reported. The experimental system consisted of a Batch reactor in which the azo dye, the semiconductor oxides and the hydrogen peroxide were mixed, whose concentrations were 0.1 mM, 100 mg/L and 65.2 mM, respectively. The mixture was homogenized by a magnetic stirrer and the pH was adjusted to 3.0. The initial volume was 500 mL. A white light lamp (127 V, 60 Hz, 362 mA, 60 W, 60 lm/W) was placed coaxial to the reactor and turned on to activate the catalyst. Samples were taken every 30 minutes to measure the absorbance, for this purpose a HACH DR3900 spectrophotometer was used. After 180 minutes of treatment, the best result, 60% degradation of the azo dye, was obtained with the mixture manganese oxides-iron oxides. The purpose of this work was to completely transform the pollutant into carbon dioxide, to avoid its adverse effects on the environment and human health, using catalysts excited with visible radiation.
