Remediation of heavy metal contaminated soils using clay minerals
-
摘要: 简要介绍了我国土壤重金属污染的现状与危害。通过粘土矿物在重金属污染土壤中净化功能的阐述,提出利用粘土矿物修复土壤重金属污染的观点。继而从天然和改性粘土矿物特性,叙述了粘土矿物修复土壤重金属污染的机制与应用进展及其影响因素。最后讨论了粘土矿物在修复土壤重金属污染过程中值得注意的几个问题,并展望了粘土矿物在该领域应用中的发展方向。Abstract: The current status and risk of soil contaminated by heavy metals in China were introduced briefly. Subsequently, this paper presented the viewpoint of heavy metal contaminated soils remediation using clay minerals based on their effective decontamination ability. Moreover, the remediation mechanisms and research progress were described by the characteristics of natural and modified clay minerals, and its impact factors were also summarized. Finally, challenges of heavy metals contaminated soils remediation using clay minerals were analyzed, and future directions relating to this aspect were discussed.
