Experimental results showed that the adulteration of iron and silver on TiO"2 could greatly improve the activity of TiO"2, and the optimum adulteration amount of iron and silver was 0.1wt.% (Fe/TiO"2) and 0.05wt.% (Ag/TiO"2), respectively, at the adulteration range of experiments. The photocatalytic degradation kinetics of X-3B on TiO"2, Fe/TiO"2 and Ag/TiO"2 were also studied. The results showed that the degradation of X-3B on all of them were in accordance with the Langmiur-Hinshelwood kinetics model well, and the sequence of apparent reaction rate constants k of X-3B degradation catalyzed by TiO"2, Fe/TiO"2 and Ag/TiO"2 was Ag/TiO"2>Fe/TiO"2>TiO"2, while adsorption equilibrium constants K"A of X-3B on Fe/TiO"2 and Ag/TiO"2 were approximately the same, and both were greater than that of TiO"2. |
