| 摘 要： | 土壤对重金属离子的吸附容量明显受阴离子配位体的影响。本文通过试验探讨了Cl~(-),SOi_4~(2-)HCO_3~(-)阴离子在不同的pH值条件下,分别对土壤吸附铜的干扰规律。运用反求吸附参数法评价了不同阴离子对铜吸附量的干扰程度,论证了土壤与地下水之间元素迁移的规律。

| Abstract: | The adsorption of trace metal ions by soil is controlled stricaly by common anion ligands concentration. The auther made a research on the influence of common anion liagands on adsorption of copper under the condition of varied pH. The important constituents contributed to disturb the adsorption of copper by soil are Cul20 and CuSO40, and that CuCl20>CuSO40, when it is in neutral or acidic soil-water systems ,and when it is in basic soil-water systems.they are Cu(OH)20,CuCO0-3,Cu(CO32-)22-,and that Cu(OH)20>Cu(CO32-)22->CuCO30. |
