| Abstract: | A solar decontamination process for water was developed using TiO 2 photocatalysts supported on attapulgite. The supported catalyst was systematically optimized with respect to catalyst dosage and calcination temperature. Methyl orange etc. azo dyes and wool textile wastewater were decolorized under solar illumination using optimal supported catalyst. The results indicates that this kind of supported catalyst illuminated by solar is very effective to destroy the most refractory compounds. and displayed high stability for circulation use. |
