摘要：
Advanced oxidation processes based on persulfate activation are promising techniques for the removal of organic compounds in aqueous solutions. In the study, iron-immobilized resin chars were prepared by different methods and used as persulfate activators for the degradation of Orange G. The results showed that iron immobilization method had a significant effect on the reactivity of activator, which might be related to the distribution and chemical states of iron and sulfur elements in the sample. The activator prepared by doping method could be used over wide pH and temperature ranges and reused char still exhibited good performance for persulfate activation.
