摘  要:
[目的]为了检测紫茎泽兰对煤渣污染土壤中重金属的富集、修复特性。[方法]采用火焰原子吸收法测定样品中重金属含量。[结果]土壤中金属含量大小顺序为Fe>Mg>Cu>Ni>Cr>Mn>Ni,Cr污染达到Ⅱ级标准;紫茎泽兰对重金属有一定的富集作用,特别是对Mg、Cr、Ni、Pb的富集系数均大于1,对Cr的转运系数为1.333。[结论]紫茎泽兰可以作为煤渣污染土壤Cr的修复植物。

摘  要:
[Objective] The research aimed to study the enrichment and phyto-remediation characteristics of heavy metals in cinder contaminated soil for Eupatorium adenophorum.[Method] 6 kinds of heavy mentals were measured by atomic absorption.[Result] The order of the heavy metal content was Fe > Mg > Cu > Ni > Cr > Mn > Ni.The concent of Cr reached the country's Ⅱ standard.Eupatorium adenophorum could enrich heavy mentals.EFs of Mg,Cr,Ni and Pb were above 1.0.TF of Cr was 1.333.[Conclusion] Eupatorium adenophorum could be used as a plant of phyto-remediation in cinder contaminated soil.
