PHOTOCATALYTIC DESTRUCTION OF WATER POLLUTANTS USING A TIO{sub}2 FILM IN PET BOTTLES

摘要

The performance of the PET bottles coated with a TiO{sub}2 was studied in this work. These bottles can be used for solar water disinfection because TiO{sub}2 combines the action of solar disinfection (SODIS) and advanced oxidation process improving the effectiveness of these technologies (Litter et al., 2005). The effect of different parameters such as initial contamination, solar radiation, etc. is analyzed using kinetics models (Salih, 2003; Horie et. al, 2005) that are validated by experiments. The contaminants studied are bacteria (E. coli) and arsenic. The behavior of the PET bottles performance is simulated with actual weather data from remote sites in Peru.
