【Abstract】 TiO₂ 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 H₂O₂ and Cu²⁺+I^- can affect the degradation rate of pyridine,adding S₂O^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.更多还原
