Article title

Surfactants removal from water and wastewater using Co modified TiO2/Al2O3 photocatalysts

Title variants
Languages of publication
The photocatalytic oxidation of Triton X-100, its oxidation products: polyethylene glycol, phenol and also commercially available wash-up liquid in water in the band reactor of our construction with supported TiO2 catalysts was studied. As a photocatalyst Co-TiO2/Al2O3 was used. The main aim of these studies was the determination of catalytic activity of Co-TiO2/Al2O3 in pollutants removal from water and the effect of O2, H2O2 or UV addition on the photooxidation. It was found that the H2O2 addition has a detrimental influence on aerated wastewater containing surfactants, and UV has an increasing effect on process. 2 hours treatment of water is enough to obtain a significant COD reduction of all studied pollutants.
