Abstract EN
The photocatalytic decolorization of industrial wastewater was investigated by using TiO2 and ZnO photocatalysts.
Heterogeneous photocatalytic processes applied under natural weathering conditions, in the presence of solar radiation show a promising degradation capability.
The complete removal of color could be achieved in a relatively short time of about 20 minutes, when ZnO was used and about 100 minutes when TiO2 was used under solar irradiation.
However, in the presence of artificial UV-light, complete decolorization of textile industrial wastewater was obtained after less than one hour of irradiation when ZnO was used and in less than two hours, when TiO2 was used at the same temperature.
The results indicate that the degree of photocatalytic decolorization of textile industrial wastewater was obviously affected by different parameters.
These parameters include catalyst mass, type of catalyst, type of reactor, type of dye, dye concentration, and temperature.
The procedure used in this research can be used as an efficient technology for solar photocatalytic decolorization of the colored wastewater discharged from the textile industry under the climatic conditions of most countries.
