| Description |
The photocatalytic degradation of Procion blue H-B dye in biodegraded
textile washwater has been investigated for the complete removal of color
and maximum reduction of chemical oxygen demand (COD). Pseudomonas
putida was utilized for obtaining biodegraded textile washwater. In this
process, silver-doped TiO2 photocatalyst was prepared and experiments
were carried out to study the effects of UV and mercury lamp irradiations
on COD reduction and removal of color. The thus prepared silver-doped
TiO2 catalyst was characterized by thermogravimetric and differential
thermal analysis, UV-visible spectrometer, X-ray diffraction, scanning
electron microscope, energy dispersive X-ray microanalysis, and BET
surface area techniques. Adsorption studies were also carried out to
evaluate the fitness of isotherm models. The results show that the
silver-doped TiO2 has enhanced the photodegradation of Procion blue
H-B dye under UV and mercury lamp irradiations. The enhanced activity
of silver-doped TiO2 is due to the enrichment of electron–hole separation
by electron trapping of silver particles.
