Degradación de sistemas colorantes con catalizadores fotoinducidos

Abstract

Este proyecto trata sobre la degradación del colorante Azul Sirius BRR (direct blue-71) utilizando el dióxido de titanio como catalizador. La degradación o eliminación de los colorantes de las aguas residuales textiles es uno de los campos más estudiados actualmente. Hoy en día hay gran variedad de estudios sobre este campo y uno de los métodos que destaca es la degradación con la ayuda de catalizadores fotoinducidos. Uno de los catalizadores más estudiados es el dióxido de titanio que es un fotocatalizador, esto significa que el catalizador necesita absorber luz para activarse y poder acelerar la reacción. En este proyecto se estudiará la cinética de la degradación de un colorante con dióxido de titanio, para entender mejor su funcionamiento. También se observarán las diferencias entre el comportamiento del dióxido de titanio cuando se encuentra bajo el efecto de luz UV y cuando no lo está.

Aquest projecte tracta sobre la degradació del colorant Blau Sirius BRR (direct blue-71) utilitzant el diòxid de titani com a catalitzador. La degradació o eliminació dels colorants de les aigües residuals tèxtils és un dels camps més estudiats actualment. Avui dia hi ha gran varietat d'estudis sobre aquest camp i un dels mètodes que destaca és la degradació amb l'ajuda de catalitzadors fotoinduïts. Un dels catalitzadors més estudiats és el diòxid de titani que és un fotocatalitzador, això vol dir que el catalitzador necessita absorbir llum per activar-se i poder accelerar la reacció. En aquest projecte s'estudiarà la cinètica de la degradació d'un colorant amb diòxid de titani, per entendre millor el seu funcionament. També cal observar les diferències entre el comportament de l'diòxid de titani quan es troba sota l'efecte de llum UV i quan no ho està.

This project deals with the degradation of the Sirius Blue BRR (direct blue-71) dye using titanium dioxide as a catalyst. The degradation or elimination of colorants from textile wastewater is one of the most studied fields today. Today there are a great variety of studies in this field and one of the methods that stands out is degradation with the help of photoinduced catalysts. One of the most studied catalysts is titanium dioxide, which is a photocatalyst, this means that the catalyst needs to absorb light to activate and accelerate the reaction. In this project, the kinetics of degradation of a colorant with titanium dioxide will be studied to better understand its operation. The differences between the behavior of titanium dioxide when it is under the effect of UV light and when it is not will also be observed.
