| 摘 要： | 用白泥作阻隔剂通过土柱浸滤实验对土壤中重金属Cu、Zn、Cr、Pb的迁移规律和阻隔效果进行了研究.结果表明:白泥对重金属Cu、Zn、Cr、Pb有显著的阻隔效果,阻隔土样中白泥的含量别为3%、5%、8%、12%,随着白泥含量的增大,滤液的p H值和阻隔土层截留的重金属量增大,滤液中重金属浓度降低.重金属的存在形态对其在土壤中的迁移特性有一定的影响,在土样中加入白泥,重金属的稳定态含量增加,对土壤中重金属的迁移产生阻隔作用.

| Abstract: | The barrier effect of white clay on the migration of heavy metals (Cu, Zn, Cr and Pb) in soil was investigated by soil column experiments. The results showed that white clay could significantly block the migration of the heavy metals of Cu, Zn, Cr and Pb. The portion of white clay added to soil were 3%, 5%, 8% and 12% respectively. The pH values of the leach solution and the amount of the metal ions retained in the soil increased with the increase of the white clay, while the concentration of heavy metal ions decreased in the filtrate. The state of heavy metal also influenced the migration characteristicsWith the addition of white clay, the stable forms of heavy metals increased, thus hindered their migration. |
