Effects of TiO2 dosage, pH and temperature on decolorization of C.I. Reactive Red 2 in a UV/US/TiO2 system

Photocatalytic reduction of phosphorus in the acid pickling milling wastewater from high-phosphorus hematite mineral processing

“…While the transmission of light would be prevented and the refl ection of light would be enhanced by the extra TiO 2 suspended in the mixture if the TiO 2 particles were much more than needed, thus the effect of the phosphorus removal was interfered. The result was consistent with the consequences of many previous documents [29,30]. Fig.…”

Advances in Heterogeneous Photocatalytic Degradation of Phenols and Dyes in Wastewater: A Review

“…Comparatively, the photocatalytic activity of Ag-TiO 2 nanoparticles was much higher than that of Degussa P25 and Yilli TiO 2 . At pH 7, the decolorization rates of Reactive Red 2 were shown to follow the order of UV/US/TiO 2 (0.94 h -1 )>UV/ TiO 2 (0.85 h -1 )>US/TiO 2 (0.25 h -1 )>US (Wu and Yu 2009).…”

Effects of TiO2 coating dosage and operational parameters on a TiO2/Ag photocatalysis system for decolorizing Procion red MX-5B

“…Sahel et al [19] and Wu and Yu [20] reported that the photocatalytic decolorization of MX-5B approximates pseudo-first-order kinetics. According to this equation, the rate constants of the photocatalytic decolorization of MX-5B by TiO 2 , the Ag carrier, and TiO 2 /Ag were calculated and the results are given in Table 3, indicating that the reaction constant of TiO 2 /Ag was obviously better than that of TiO 2 .…”
