Abstract: C1.00098 : Photocatalytic Activity of TiO$_{2}$ Thin Films Obtained by the Sputtering RF in Wastewater
Author:
The photocatalytic activity of TiO$_{2}$ thin films in
wastewater, under an
UV irradiation, is studied. The films were prepared on corning glass
substrates by the sputtering RF technique. We present evidence on
the
photocatalytic degradation, carried out by advanced oxidation
processes
(AOPs) in domestic wastewater pretreated with UASB (upflow
anaerobic sludge
blanket) reactors. TiO$_{2}$ films were illuminated with
ultraviolet light
during a time of 4 hours ($\lambda \quad \cong $ 264 nm). We
could see the
effect of degraded operation in the absorbance measurement using
UV-VIS
spectrophotometry. The results show an increased rate of
degradation of the
wastewater by 30{\%} compared to the values reflected
biologically treated
wastewater by anaerobic reactors.
