| Abstract: | Photocatalytic degradation of three kinds of contaminants including sulfosalicylic acid, H acid and product of phenol treated by wet air catalytic oxidation was investigated in order to test the activity of Ag/TiO_2 (1.0 wt%). For the photocatalytic degradation of sulfosalicylic acid and H acid, Ag/TiO_2 showed higher activity than that of TiO_2 catalyst. For the effluent of phenol treated by wet air catalytic oxidation, Ag/TiO_2 photocatalysis can remove the color efficiently, but the removal of COD was low. |
