【摘要】 土壤Cd污染已成为严重的环境和公共健康问题,日益受到人们的密切关注,利用粘土矿物修复Cd污染土壤是一种行之有效的技术。为了实现重金属Cd污染土壤能有效快速修复,本研究在总结粘土矿物性能的基础上,分析了粘土矿物对重金属Cd污染土壤的影响因素,主要包括粘土矿物的类型、用量、改性及土壤pH、污染程度,概括了其修复机理,吸附作用和沉淀作用,结果显示修复效果良好。最后,提出了该领域的研究方向。更多还原

【Abstract】 Soil cadmium pollution has become a serious environmental and public health problem, which has gained increasingly close attention from people, using clay minerals remediation Cd contaminated soil was an effective technique. In order to promote the rapid development of remediation in heavy metal contaminated soil effectively, the paper summarized the influence factors of clay minerals in remediation of soil Cd, including the type, dosage and modification of clay minerals, and soil pH, degree of soil pollution et al, analyzed its remediation mechanism of adsorption and precipitation on basis of the study properties of clay minerals, results showed that remediation effect was good. Finally, the paper put forward the future direction of research in this field.更多还原
