摘　　要：铁氧化物及其前体在重金属污染土壤的原位修复方面已得到广泛应用,它既可单独使用亦可与其他钝化剂联用。尽管应用铁氧化物修复重金属污染土壤取得了部分成功,但对长期、大规模应用的效果及其稳定性等,目前尚缺乏统一的认识。在对铁氧化物修复重金属污染土壤研究结果进行归纳总结的基础上,探讨了植物和微生物对铁氧化物稳定砷效果的影响,旨在为污染土壤修复提供理论支撑。Iron(hydr)oxide and its precursors have been widely used in the in-situ remediation of heavy metal contaminated soils.It can be used alone or in combination with other passivating agents.Although the application of iron oxides to remediate heavy metal contaminated soil has achieved partial success,there is still a lack of a unified understanding of the effects and stability of long-term and large-scale applications.Based on the summary of the results of iron oxide remediation of heavy metal contaminated soil,the effects of plants and microorganisms on the stabilization of arsenic by iron(hydr)oxide were discussed,aiming to provide theoretical support for the remediation of contaminated soil and the stabilization of pollutants.
