摘　　要：硫化零价铁(S-ZVI)包括纳米级S-ZVI(S-nZVI)和微米级S-ZVI(S-mZVI),作为零价铁(ZVI)的改性材料,具有更强的反应活性和目标污染物选择性,对水体中重金属和有机污染物有更好的去除及固定化效果,因此受到越来越多研究者的关注。综述了近年来S-ZVI的制备方法、硫化对物理化学特征和反应活性的影响。相对于ZVI,S-ZVI的反应速率和去除效率都有所提高,同时减缓了ZVI与水的反应,增加了对目标污染物的选择性并延长了反应时间,对于水及土壤中的污染物修复具有重要意义。As the modi ed materials for zero-valent iron(ZVI),sul de-modi ed zero-valent iron(S-ZVI)including sul de-modi ed nanoscale ZVI(S-nZVI)and sul de-modi ed microscale ZVI(S-mZVI)has stronger reactivity and target pollutant selectivity.In addi-tion,it has better removal and immobilization effects on heavy metals and organic pollutants in water.Therefore,there are increasingly number of researchers attaching more importance to S-ZVI.In recent years,the preparation methods of S-ZVI and the effects of sul de-modi ed on physicochemical characteristics and reactivity were reviewed.Compared with ZVI,the reaction rate and removal ef ciency of S-ZVI are improved.At the same time,it slowed down the reaction of ZVI with water.Moreover,S-ZVI showed the higher selectivity at the target pollutants and prolonged the lifespan of ZVI,which was of great signi cance for the remediation of pollutants in water and soil.
