Infona service will be unavailable from 2016-10-25 22:00 to 2016-10-25 22:20 due to maintenance works planned for this time.
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.
