| Abstract: | TiO_2 was used to degrade methyl orange solution with ultraviolet radiation.The effect of several regents on photocatalytic degradation of pyridine solution was investigated in details.The results reveal that additions of H_2O_2 and Cu~(2 ) I~(-) can affect the degradation rate of pyridine,adding S_2O~(2-)_8,IO~-_4 and Ag~( ) can accelerate the degradation rate of pyridine.Further attention should be focus on the effect of ions on the photooxidation of dyes in practice. |
