摘　　要：铁基材料因环境友好、价廉易得已被广泛应用于过硫酸盐高级氧化体系,但仍存在pH适用范围窄和重复利用性差等问题,在过硫酸盐技术中的应用受到限制。目前,利用化学反应和物理效应来提高铁基材料活化过硫酸盐效率的方法已被行业学者们关注并大量研究。该文强调了利用化学反应(无机还原剂、有机配位剂、绿色氧化剂)和物理效应(光辐射、电化学、弱磁场、超声波、微波场)协同铁基材料活化过硫酸盐的巨大潜力,分析了各种物理效应和化学反应协同铁基材料活化过硫酸盐的协同机制,总结了铁基材料协同活化过硫酸盐技术的研究进展。文章提出了铁基材料协同活化过硫酸盐氧化技术在未来的研究和实际应用中可能面临的挑战和实际问题,展望了协同铁基材料活化过硫酸盐氧化技术发展方向和应用前景。Iron-based materials have been widely used in the advanced oxidation system of persulfate due to their environmental friendliness and low cost,but there are still problems such as narrow pH applicability and poor reusability,which limit the application in persulfate technology.Currently,the use of chemical reactions and physical effects to improve the efficiency of iron-based materials for activation of persulfate has been paid attention to and heavily studied by industry scholars.The great potential of using chemical reactions(inorganic reductants,organic ligands,green oxidants)and physical effects(optical radiation,electrochemistry,weak magnetic field,ultrasonic wave,microwave field)to synergistically activate persulfate by iron-based materials is emphasized,the synergistic mechanism of various physical effects and chemical reactions to synergistically activate persulfate by iron-based materials is analyzed,and the research progress of synergistic activation of persulfate by iron-based materials technology is summarized.The challenges and practical problems that may be faced in the future research and practical application of the synergistic activation of peroxynitrite oxidation by iron-based materials are presented.Finally,the development direction and application prospects of synergistic iron-based materials activated persulfate oxidation technology are foreseen.
