| 摘 要： | 研究通过模拟土柱淋溶实验来研究污泥土地利用中重金属铜在土壤中的迁移行为。结果表明污泥土地利用会明显增加土壤中铜的总量,但大部分集中在40 cm以上的土壤中。通过BCR连续提取法发现,经淋溶后耕作层（0 cm~30 cm）土壤中的铜仍然以残渣态为主（占50%以上）,但能被植物利用的酸溶/可交换态和可还原态铜有了明显的增加。与去离子水相比,模拟酸雨（pH=4.5）会使土壤中铜的淋溶强度增加,并更能促使其向下迁移。

| Abstract: | The migration of Copper(Cu) in soil amended with sewage sludge compost through eluviating simulated soil column was investigated in this paper.The result showed that the concentration of Cu in soil increased significantly when applying sewage sludge compost in land and most of it concentrated in the topsoil of 0 cm~40 cm.It was indicated that the Cu in plough horizon(0 cm~30 cm) existed mostly as residual fraction(>50%) through the BCR sequential extraction procedure,but the acid soluble fraction and exchen... |
