Simultaneous Photoreduction of Cr(Ⅵ) and Photooxidation of Methyl Orange in Water Induced by Fe(Ⅲ)-OH Complex

  • 摘要: 在250 W照明金属卤化物灯(λ≥313 nm)照射下,Fe(Ⅲ)-OH配合物能同时引发水中Cr(Ⅵ)的光还原和偶氮染料甲基橙的光氧化,并且同时Cr(Ⅵ)光还原和甲基橙光氧化效率都较Fe(Ⅲ)-OH配合物单独作用下的效率有明显提高.在c(Fe(Ⅲ)),c(Cr(Ⅵ))和c(甲基橙)为25~200 μmol/L时,pH=3.0是最佳值;c(Fe(Ⅲ))的增加同时有利于Cr(Ⅵ)光还原和甲基橙光氧化;c(Cr(Ⅵ))为25 μmol/L时,其自身光还原的初始速率最大,甲基橙光氧化反应初始速率则随c(Cr(Ⅵ))和c(甲基橙)的增大而减小.
