Degradation of Acid Red 27 in Sunlight Using TiO₂

Abstract:

The treatment of highly colored wastewater containing hazardous industrial chemicals and dyes is one of the growing needs of the present time. To meet the motive in the present work, TiO₂ was immobilized on glass slides using heat method and acrylic binder. Heat method involves the preparation of suspension of powdered TiO₂ and then brushing the suspension on the surface of glass slides. The slides were then calcined at high temperature for attachment of TiO₂ to the glass surface. The acrylic binder method of immobilization involves preparation of acrylic emulsion and using the same to attach the TiO₂ particles to the fiber glass slides. The preared films were then characterized using XRD and SEM. The photocatalytic performance of the prepared films for degradation of Acid Red 27 dye in sunlight was evaluated and compared. The films formed with the help of heat treatment method showed better dye degradation capabilities.
