摘　　要：建立了零价铁还原催化臭氧氧化靛蓝二磺酸钠的体系,通过一级动力学分析分别考察了零价铁粒径、底物初始浓度、零价铁的投加量、pH、温度以及废水中常见的阴离子(Cl^-、NO_3^-、SO_4^(2-))等条件对反应速率的影响。通过自由基抑制试验与电子自旋共振法(ESR)以及离子阱质谱等实验分析来进一步探讨零价铁还原催化臭氧氧化体系的反应机理。A system for the reduction,catalysis and ozonation of Indigo disulfonate with zero-valent iron has been established. The influences of the grain diameter of zero-valent iron,substrate initial concentration,dosage,pH,and temperature,along with common anions,such as Cl-,NO3-,SO42- etc. in wastewater on reaction rates are investigated,respectively,by the first-order kinetics analysis. The reaction mechanisms of reduction,catalysis and ozonation systems of Indigo disulfonate with zero-valent iron are further discussed,by means of experiments and analysis,such as radical inhibition test,electron spin resonance（ESR）and ion trap mass spectrometry,etc.
