| 摘 要： | 采集不同酸碱度的4种土壤样品，采用人工外源添加方式配制As、cu、Ni、Pb和zn污染土壤，并应用Tessier、BCR和TCLP对土壤中重金属的活性部分进行提取，结果表明，BCR能较合理地提取出酸性土壤中的活性部分重金属，Tessier能较合理地提取出碱性土壤中的．活性部分重金属；对不同性质土壤中重金属进行形态提取应采用不同的提取方法。

| Abstract: | Four kinds of soil samples with different pH values were collected and the synthetically heavy metals contaminated soils were obtained by adding the corresponding metal salts.Tessier,BCR and TCLP extraction techniques were employed to extract heavy metals available fraction.The results illustrated that BCR was suitable to extract heavy metals available fraction for acidic soils whereas Tessier was suitable for alkaline soils.In order to extract heavy metals available fraction in soils correctly,different se... |
