| 摘 要： | 对土壤中常见的三种粘土矿物对Pb2+的吸附作用及其主要影响因素进行了探讨。结果表明，三种粘土矿物对Pb2+的吸附能力顺序为：蒙脱石＞伊利石＞高岭石。蒙脱石对Pb2+的吸附受pH的强烈影响，pH高有利于对Pb2+的吸附。与蒙脱石形成复合体形式的有机化合物的存在不利于蒙脱石对Pb2+的吸附。

| Abstract: | The adsorption of Pb2+ and on three clay minerals its major affecting factors are studied in this paper. The resu1ts show that the adsorbing ability of these clay minerals follows the order of montmorillonite> kaolinite> illite. The adsorption of Pb2+ on montmorillonite is affected greatly by pH, i. e., higher pH is favorable to Pb2+ adsorption. Complex organic materials are unfavorable to the adsorption of Pb2+. |
