摘要

A batch photo-fluidized bed reactor was designed, and a novel immobilized iron oxide catalyst called "B1" was utilized for the heterogeneous photo-Fenton degradation of reactive black B (RBB). This catalyst adsorbs RBB well and can markedly accelerate the degradation of RBB under ultraviolet irradiation at λ=365nm. Effects of ultraviolet intensity, RBB concentration, H2O2 concentration, and the amount of B1 catalyst on RBB degradation were determined. It was found that removal of RBB could be up to 98% at [B1]=5g/L, [H2O2] 0=63.75mg/L, [RBB]=100mg/L, and pH=4 in 180min. Moreover, the most attractive quality of the B1 catalyst is that it can facilitate nearly total RBB desorption under alkali conditions (pH=12), indicating high reusability for industrial applications.
