| Abstract: | [ Objective ] The research aimed to study the enrichment and phyto-remediation characteristics of heavy metals in cinder contami- nated 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 ade~to- phorum could enrich heavy mentals. EFs of Mg, Cr, Ni and Pb were above 1.0. TF of Cr was 1. 333. [ Conclusion] Ezq~atorium adenophorum could be used as a plant of phyto-remediation in cinder contaminated soil. |
