The Comparison of Photocatalytic Degradation and Decolorization Processes of Dyeing Effluents
Figure 2
Absorption and decolorization spectra of WPac (a), WLeat (b), WFlax (c), and WCot (d). Solid line (red): initial spectrum of effluent, ; dotted line (blue): effluent with TiO2, without UV-a irradiation, ; solid line (blue): effluent with TiO2, after UV-a irradiation, ; (●) total decolorization of effluent with TiO2 (2.5 g L−1) and after UV-a irradiation; (◯) decolorization of effluent as a result of the photocatalytic process in the presence of TiO2 (2.5 g L−1) and after UV-a irradiation.
