摘要 铁基材料可通过降低重金属的有效态比例,降低土壤重金属的生物可利用性,控制重金属毒性危害,具有来源广、生产成本低、稳固效果优良等优势。参阅国内外相关文献,对铁基材料在农田土壤修复过程中存在的作用机理如吸附沉淀、还原、氧化等,以及影响因素如土壤水分、pH、有机质含量和离子竞争等进行了阐述。对铁基材料在土壤重金属污染的修复潜力以及未来研究方向进行了相关展望。 Iron-based materials can reduce effective state heavy metals proportion and heavy metals bioavailability in soil,and control heavy metals toxicity.There are advantages of wide source,low production cost and good stable effect.Operation mechanism of iron-based materials during soil heavy metals remediation such as adsorption,precipitation,reduction,oxidation,as well as influencing factors such as soil moisture,pH value,organic content and ion competition were summarized and discussed though referring to domestic and overseas literatures.Potentiality and future research direction of ironbased materials remediation in heavy metal contaminated soil were expected.
