摘要
Pb分配系数是描述Pb在地下水中迁移性质的重要参数。研究对象和目的不同 ,计算Pb分配系数的方法也不同。静态吸附平衡实验方法简便易行 ,适用于计算不同岩性的Pb分配系数 ;动态土柱实验方法难度较大 ,主要用于建立Pb迁移方程 ;阳离子交换系数方法计算过程复杂 ,适用于解决野外实际问题。
The distribution coefficient of Pb is an important parameter to describe the migration characteristics of Pb in groundwater. For different objects and aims, the methods of calculating the distribution coefficient of Pb are also different. The method of static examination of equilibrium adsorption is simple and fits to calculate the distribution coefficient of Pb for any soil. The method of dynamic examination of soil column involves more difficulties and fits to build the migration equation of Pb. The method of exchange coefficient of cations involves a complex calculation procedure and fits to solve field problems.
