恬矿库周围土壤中重金属存在形态特征研究

Study on Characteristics of Heavy Metal Species in the Soils Near the Tailings

摘要: 通过对大冶铜绿山铜铁矿尾矿库周围土壤中重金属形态分析实验，研究了重金属各种形态在土壤中的分布特征。由对比实验可知，尾矿库周围土壤中Ｃｕ、Ｐｂ、Ｚｎ、Ｃｄ等重金属含量都显著地高于对照样品，书经受到重金属的严重污染。土壤中重金属形态分布征为：ｗ（Ｃｒ、Ｚｎ、Ｆｅ）；可变换态〈碳酸盐态〈有机态〈铁锰氧化态〈残渣态；ｗ（Ｃｕ、Ｐｂ）：可变换态〈碳酸盐态〈有机态〈残渣态〈铁锰氧化态；ｗ（Ｃｄ）：残渣态，有机

Abstract: Distribution characteristics of the heavy metal species in soils were studied by speciation analysis of heavy metals in the soils near Cu Fe tailings in Daye. The results show that the contents of Cu, Pb, Zn and Cd in soils near the tailing area are sign
