| 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。

| Abstract: | As the modified materials for zero-valent iron (ZVI), sulfide-modified zero-valent iron (S-ZVI) including sulfide-modifiednanoscale ZVI (S-nZVI) and sulfide-modified microscale ZVI (S-mZVI) has stronger reactivity and target pollutant selectivity. In addition, it has better removal and immobilization effects on heavy metals and organic pollutants in water. Therefore, there are increasinglynumber of researchers attaching more importance to S-ZVI. In recent years, the preparation methods of S-ZVI and the effects of sulfidemodified on physicochemical characteristics and reactivity were reviewed. Compared with ZVI, the reaction rate and removal efficiencyof S-ZVI are improved. At the same time, it slowed down the reaction of ZVI with water. Moreover, S-ZVI showed the higher selectivityat the target pollutants and prolonged the lifespan of ZVI, which was of great significance for the remediation of pollutants in water andsoil. |
