At the heavy metal concentration of 3-4ppm, our study on adsorption capacity, adsorption selectivity of montmorillonite, illite and kaolinite to Cu〓、 Pb〓、 Zn〓、 Cd〓、 Cr〓 shows that the adsorption capacity is mainly determined by the capacity of exchangeable cations and the adsorption capacity of the three clay minerals decreases in this sequence: montmorillonite ＞＞ illite＞kaolinite. It is found that clay minerals have obvious adsorption selectivity to various heavy metals. Montmorillonite exhibits a stronger affinity to Cr〓 and Cu〓 while kaolinite and illite sorb Cr〓 and Pb〓 more effectively. At the same heavy metal concentration, adsorption amount of clay minerals to heavy metals increase with increasing pH value of the solution.

在痕量浓度下，研究了蒙脱石、伊利石、高岭石三种粘土矿物对Cu〓、Pb〓、Zn〓、Cd〓、Cr〓五种重金属离子的吸附容量、吸附选择性及其介质条件对吸附量的影响，结果表明，粘土矿物的阳离子交换容量越大，对重金属离子的吸附容量也越大，其大小顺序为蒙脱石＞＞伊利石＞高岭石；同时，不同粘土矿物对重金属离子具有明显的吸附选择性，蒙脱石对Cr〓和Cu〓有较好的选择性，伊利石和高岭石则对Cr〓和Pb〓有较好的选择性；随着吸附溶液pH值的增大，其吸附量有增加的趋势。
