Speciation Analysis of Heavy Metals of Core Amuta Sediments in Lianhua Lake

摘要：

The BCR-SEP method was used to determine the binding forms of heavy metals in Amuta Lake(AMT) in this paper.The chemical forms of heavy metals,namely extractable fractions or valid fractions,including exchangeable-carbonate fraction,Fe-Mn oxide fraction and Organic-sulfide fraction .The results of the partitioning study indicated that in the core AMT sediments,Cr,Fe and Ni are mainly associated with the residue fraction,Cu is mainly concentrated in the Fe-Mn oxide fractions and residue fraction,Mn is concentrated in the exchangeable-carbonate fraction and residue fraction.Zn is concentrated in organic-sulfide fraction and residue fraction.
