In view of its high TiO2 content, the photocatalytic activity of this material was tested in the degradation of humic and fulvic acid substances (HFAs) and showed low levels of photoactivity, as was the case for the commercial photocatalyst Aeroxide TiO2 P25 (P25). However, due to its high Fe3+ content, an important application was observed for WTiO2 as an HFA coagulant and catalyst in Fenton and photo-Fenton processes. A two-stage process of coagulation and photo-Fenton treatment was subsequently designed and conducted at laboratory and small pilot scale. High percentages (above 95%) were obtained in total organic carbon (TOC) removal. | URI: | http://hdl.handle.net/10553/43224 | ISSN: | 1944-3994 | DOI: | 10.1080/19443994.2016.1159994 | Fuente: | Desalination and Water Treatment [ISSN 1944-3994], v. 57 (54), p. 26211-26221 |
