摘要：

The effect of annealing temperature of Fe78Si9B13 amorphous ribbons for activation of persulfate on azo dye Orange G degradation was investigated. The ribbons annealed below 623 K have very rapid degradation rate, and the degradation efficiency within 10 min was 97%. The kinetic analysis elucidated that the degradation process could be described by pseudo-first-order kinetic model. The reaction rate was not strictly decreased with the increasing annealing temperature. In particular, the ribbons with different structures by annealing at different temperatures, after the reaction, show obviously discrepant surface corrosion morphology which also plays a role in the reaction rate.
